I am writing a logic app. My schema looks like below.
i am able to select the dynamic content at each step. I am have 4 "for each" operations for the 4 arrays.
However when i test through postman ,
i get the error at " for each " step.
"InvalidTemplate. Unable to process template language expressions for action 'For_each_items' at line '1' and column '1710': 'The template language expression 'triggerBody()?['Data']?['Orders_items']' cannot be evaluated because property 'Data' cannot be selected. Property selection is not supported on values of type 'String'. Please see https://aka.ms/logicexpressions for usage details.'"
I think when you use postman to test, you need to select the body type as json：

Sorry if this is a bit vague or rambly, I'm still getting to grips with Data Factory and a lot of it seems a bit obtuse...
What I want to do is query my Cosmos Database for a list of Ids of records that need to be updated. For each of these records, I want to call a REST API using the Id (i.e. /Record/{Id}/Details)
I've created a Data Flow that took a string as a parameter and then called the REST API fine.
I then made a pipeline using a Lookup with a query (select c.RecordId from c where...) and pass that into a ForEach with items set to #activity('Lookup1').output.value
I then setup the Activity of the ForEach to my Data flow. From research, I think I'm supposed to set the Parameter value to "#item().RecordId", but that gives an error "parameter [name] does not match parameter type 'string'".
I can change the type of the parameter to any (and use toString([parameter]) to cast it ) and then when I try and debug it passes the parameter in, but it gives an error of "Job failed due to reason: at (Line 2/Col 14): Datatype any not found".
I'm not sure what the solution is. Is there a way to cast the result of the lookup to an integer or string? Is there a way to narrow an any down? Is there a better way than toString() that would work? Is there a better way than ForEach?
I tried to reproduce similar scenario what you are trying.
My sample data in cosmos
To query Cosmos Database for a list of Ids and call a REST API using the Id For each of these records.
First, I took Lookup activity in data factory and selected the id's where the last_name is Bluth
Its output and settings are as below:
Then I passed the output of lookup activity to For-each activity.
Then inside for each activity I created Dataflow activity and for that DataSource I gave the source as Rest API. My Rest API to call specific user is https://reqres.in/api/users/2 I gave base URL as https://reqres.in/api/users.
Then I created parameter called demoId as datatype string and in relative URL I gave that dynamic value as #dataset().demoId
After this I gave value source parameter as #item().id as after https://reqres.in/api/users there is only id should be provided to get data in you case you can try Record/#{item().id}/Details.
For each id it is successfully passing id to rest API and fetching data:
Trying to add values from the JSON Parser into a dynamic Oracle query but always shows up as blank/empty.
Same results trying to use the formal parameters and declaring them within the Oracle query as well.
Is this possible?
Service Bus trigger. Message comes in and goes into the "For each message" loop. It then gets parsed in the "Parse JSON Message" and when I try to use the dynamic content from that in an Oracle query (e.g. #body('Parse_JSON_Message')?['contentData']?['dynamicValue']), they always show up as nothing/blank.
I can use this same reference later (again #body('Parse_JSON_Message')?['contentData']?['dynamicValue']) with no issues but it always ends up blank in the query.
Even using formal parameterized key values shows the #body('Parse_JSON_Message')?['contentData']?['dynamicValue']) to be NULL.
So my queries are coded as:
SELECT thisValue
WHERE columnName = #body('Parse_JSON_Message')?['contentData']?['dynamicValue'] (have also tried #{body('Parse_JSON_Message')?['contentData']?['dynamicValue']})
But are coming out as:
SELECT thisValue
WHERE columnName =
...with no result obviously.
This query does work if I hard code the value.
If I use dynamic values in my output (where I'm mapping data), it works fine. So how should I correctly dynamic values in this Oracle query?
I have created an Azure Logic App by adding Execute a SQL query (V2) action. In the Execute a SQL query action, I have used the following query to get the specific column data.
select XXXX from [dbo].[XXXX] where XXXX=#{triggerBody()?['XXXX']?['XXXX']}
I’m getting the column data by using the following expression:
body('Execute_a_SQL_query_(V2)')?['resultsets']?['Table1'][0][<'Name of table column'>]
But for some scenarios Execute a SQL query action returns the following response:
{
"ResultSets": {},
"OutputParameters": {}
}
Whenever Execute a SQL query action returns empty response, then I'm getting the following error:
InvalidTemplate. Unable to process template language expressions in action 'Set_variable' inputs at line '0' and column '0': 'The template language expression 'int(body('Execute_a_SQL_query_(V2)')?['resultsets']?['Table1'][0]['XXXX'])' cannot be evaluated because property '0' cannot be selected
So, can anyone suggest me how to validate the “ResultSets” object is null or not?
You can use the below expression and conditions to evaluate if the ResultSets are empty and then proceed with further steps.
equals(string(outputs('Execute_a_SQL_query_(V2)')?['body']['ResultSets']),'{}')
Example:
If its true, that means it empty set.
I require some help on being able to get around displaying an endpoint from a SOAP Request.
Below I have a piece of code which retrieves an endpoint from a SOAP Request named 'TestAvailability' and outputs it to a file (the code is within a groovy script step).
def endpoint = testRunner.testCase.getTestStepByName('TestStep').get
Now here is the catch, in the file it outputs the endpoint as so:
ENDPOINT: ${#Project#BASE_URL}this_is_the_endpoint
The reason it displays ${#Project#BASE_URL} is because this is a variable set at project level so that the user can select their relevant environment from a drop down menu and that value will be displayed for the variable: ${#Project#BASE_URL}
But I don't want the project variable to be displayed but instead its value like so if ${#Project#BASE_URL} is set to 'testenv'
ENDPOINT: testenv_this_is_the_endpoint
My question is how do I change the code in order to display the endpoint correctly when outputted to a file?
You have a trivial issue. Since it is using property expansion in the endpoint, it request to expand it.
All you need is to change below statement
From:
testResult.append "\n\nENDPOINT: " +endpoint
To:
testResult.append "\n\nENDPOINT: ${context.expand(endpoint)}"
I am getting below error when I run the Orchestration and try to assign value to a promoted property by reading the value of another promoted property.
Error in Suspended Orchestration:
Inner exception: There is no value associated with the property BankProcesses.Schemas.Internal_ID' in the message.
Detail:
I have 2 XSD schemas, 1 for calling a stored procedure and reading its response and another to write it into a flat file. The internal ID returned in the response from SP needs to be passed to a node in another XSD schema to write to a flat file format.
I have promoted an element from the response schema and also promoted an element from the schema to write to flat file. I am assigning the value to promoted propeties as below:
strInternalId = msgCallHeaderSP_Response(BankProcesses.Schemas.Internal_ID);
msgCallSP(BankProcesses.Schemas.Header_Internal_ID) = strInternalId;
But when I run the orchestration I get the error as mentioned above. I have checked the reponse from stored procedure and the reponse XML does contain some value but I am unable to assign that value to another schema. Please advice
Thanks,
Mayur
You can use exists to check the existence of property.
if(BankProcesses.Schemas.Internal_ID exists msgCallHeaderSP_Response)
{
strInternalId = msgCallHeaderSP_Response(BankProcesses.Schemas.Internal_ID);
msgCallSP(BankProcesses.Schemas.Header_Internal_ID) = strInternalId;
}
One scenario that might cause this error is that there is no Header_Internal_ID element in the message you are trying to modify. Can you inspect the message before modification to ensure that there is an element whose value should be changed - drop the message out to a file location, maybe.
If this is the case, then just ensure that you create this element when you instantiate you r message for the first time - even if you initially set it to an empty element.
HTH
To check if the property exists, you can use this syntax:
BMWFS.LS.BizTalk.CFS.BankProcesses.Schemas.Internal_ID exists msgCallHeaderSP_Response
However, if the case is that the source field would always be there, you have to work backwards to find out why the Property is not appearing on the Context.
If it's coming from a Port, is the message passign through an XmlDisassembler Component? If it's coming from another Orchestration, are you actually setting the Property?
The easiest way to look at the Context is to route the Message, msgCallHeaderSP_Response, to a Stopped Send Port. You can then view the Context in BizTalk Administrator.
