I am making an authorized call from the using token. Firstly the user gets a token after sign in, I stores that token in shared preferences, and passed that token(stored as string) as header to retrofit api call using okhttp as client. Now getting this error. How to encode the header/ token or remove this error.
[example of token I get from API : "Du_jwJP64Znbwc1EvyJMEkw9HHwIZPjYnXgchiq5e2Tf24y9vNBrD6PJX8jTMj7qGDQyxTDBW8XrlwSRBjNQ-Tzzafq7r3jS5x9ZsXJgU9JgDi8ZNmwf_JD47aTRUKEhX5KtZ52oOeiuOnjO9XKCKT2g1vLpmcpUxvOi36R6ySNoMBmWzn7KmG6_vZzhfT0YhhfIW8x6vPEHmDLvBIIWbBDry0qpoiZNkgkI2D6CkFqQN1Hy-fMc3tFX7Y-VPRBF6bXQOHbsDAPkSqFfVxMQaw "]

You have an extra space in your #Header annotation on your service interface.

We have a basic servicestack frontend that sends using the jsonclient to backend services and works for the past few years.
I am trying to investigate why we are receiving the below exception on any frontend JSON Client.get requests,
System.NullReferenceException
Object reference not set to an instance of an object.
System.NullReferenceException: Object reference not set to an instance of an object.

It's strange, and i'm trying to reproduce this issue by hitting the breakpoint, and nulling / modifying the headers, but can't reproduce or figure out what this issue is.
To me, doesn't the exception imply the header base keys are null, and it can't be retrieved - but how does that occur ?
Using ServiceStack 5.80
ASP.NET MVC
.Net Framework 4.6.1
EDIT:
Calling line of code that produces this issue is
var deviceResult = client.Get(new DRequest{ U = r.D });
Trying to use the replyChannel for sending an error response for the WebFlux.inboundGateway, however no response is sent from ErrorFlow and the client continues to wait for response. Kindly suggest.
return IntegrationFlows.from(WebFlux.inboundGateway("/some/uri")
.requestMapping(m -> m.methods(POST))
.requestPayloadType(SomeObject.class)
.replyChannel(webReplyChannel)
.errorChannel(appErrorChannel))
#Bean
public IntegrationFlow appErrorFlow() {
return IntegrationFlows.from(appErrorChannel())
.<ErrorMessage, Message<String>> transform(errorMessage -> MessageBuilder.withPayload("Error Response")
.copyHeaders(((MessagingException) errorMessage.getPayload()).getFailedMessage().getHeaders())
.build())
.get();

This is known framework limitation: https://github.com/spring-projects/spring-integration/issues/3984.
So, for now you have to do like this instead:
.transform(Message.class,
errorMessage ->
MessageBuilder.withPayload("Error Response")
.copyHeaders(((MessagingException) errorMessage.getPayload()).getFailedMessage().getHeaders())
.build())
Only those getFailedMessage().getHeaders() contain respective replyChannel and errorChannel headers.
I have the following code to send a email through EWS API,
ExchangeService service = new ExchangeService();
service.setUrl(new URI(**MyExchangeURL**));
ExchangeCredentials credentials = new WebCredentials(**UserName**, **Password**);
service.setCredentials(credentials);
EmailMessage message = new EmailMessage(service);
message.setSubject("EWS Test Mail");
message.setBody(MessageBody.getMessageBodyFromText("This is a test mail from EWS"));
message.getToRecipients().add("Test#gmail.com");
message.send();
With the above code, I facing a null pointer exception when message.send() is called.

When debugged further there is a mismatch in the attribute name.
In request, the attribute is contentType is setted in request. But while reading the response, we are getting Null as code used have Content-type. There is a mismatch in the attribute name being set and read.
Is anyone else facing this issue or any workaround?
To register a webhook on Dynamics 365 there is a tool called Plug-in Registration (https://learn.microsoft.com/en-us/powerapps/developer/data-platform/register-web-hook).
However, I would like to automate the webhook registration process and thus would like to use the Web API endpoint for webhook registration:
/api/data/v9.2/serviceendpoints
The problem I have is the setting of the value for the parameter authvalue in the JSON request body, because I want to use Http Header authtype:
{
"name": "Test Webhook",
"url": "https://myendpoint",
"contract": 8,
"authtype": 5,
"authvalue": "<========= ??? what comes here ???"
}
Assuming I want to have this header be sent to my webhook endpoint:
Authorization: Basic dXNlcm5hbWU6cGFzc3dvcmQ=
What would be the value of authvalue in the JSON above ?
The value should be a string according to the data type of authvalue, but how that should be formatted?
If I use the value Authorization: Basic dXNlcm5hbWU6cGFzc3dvcmQ= as is for authvalue,
when the webhook is fired, I got the following error in System Job:
Plugin Trace:

I have this exception message thrown when accessing into this Google Site via Google Sites API. There is no problem when accessing other Google Sites with via Google Sites API.
This is the programming:
private static ContentFeed getFirstContentFeed(SitesService service, String siteName, Credential credential) throws Exception {
// Configure URL as Google Sites content feed
String url = String.format(
"%s/%s/%s",
GoogleOAuth2Constant.GOOG_SITES_CONTENT_FEED,
ReadXmlConfigurationService.getNode("domain"),
siteName);
// Assign Google credential into SitesService
service.setOAuth2Credentials(credential);
// Use HTTP-SSL to call Google Sites API
service.useSsl();
// Retrieve site contents
return service.getFeed(new URL(url), ContentFeed.class);
}
This line caused the exception thrown:
return service.getFeed(new URL(url), ContentFeed.class);
Well, I don't think my programming portion caused the issue because it somehow managed to be called after retries.
Had it solved by adding setConnectionTimeout()
private static ContentFeed getFirstContentFeed(SitesService service,
String siteName,
Credential credential) throws Exception {
// Configure URL as Google Sites content feed
String url = String.format(
"%s/%s/%s/",
GoogleOAuth2Constant.GOOG_SITES_CONTENT_FEED,
ReadXmlConfigurationService.getNode("domain"),
siteName);
// Assign Google credential into SitesService
service.setOAuth2Credentials(credential);
// Use HTTP-SSL to call Google Sites API
service.useSsl();
// Set HTTP timeout for 2 minutes for larger feed
service.setConnectTimeout(120000);
// Retrieve site contents
return service.getFeed(new URL(url), ContentFeed.class);
}
