B2C custom policy : The method or operation is not implemented - azure-ad-b2c

Question

I try to create an orchestration step that just set the value of a claim. I used the starter pack scenarios/phone-number-passwordless/Phone_Email_Base.xml as a sample with the DoesStrongAuthEmailExist TechnicalProfile So basicaly I have a Claim :
<ClaimType Id="isThisAvailable">
<DisplayName>Determines if something is available in an environment</DisplayName>
<DataType>string</DataType>
</ClaimType>
A claim transformation method :
<ClaimsTransformation Id="SetThisIsAvailableClaim" TransformationMethod="CreateStringClaim">
<InputParameters>
<InputParameter Id="value" DataType="string" Value="false" />
</InputParameters>
<OutputClaims>
<OutputClaim ClaimTypeReferenceId="isThisAvailable" TransformationClaimType="createdClaim" />
</OutputClaims>
</ClaimsTransformation>
A claim provider with TechnicalProfile :
<ClaimsProvider>
<DisplayName>Availability check</DisplayName>
<TechnicalProfiles>
<TechnicalProfile Id="CheckIfThisIsAvailable">
<DisplayName>Test</DisplayName>
<Protocol Name="Proprietary" Handler="Web.TPEngine.Providers.ClaimsTransformationProtocolProvider, Web.TPEngine, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" />
<InputClaimsTransformations>
<InputClaimsTransformation ReferenceId="SetThisIsAvailableClaim" />
</InputClaimsTransformations>
<OutputClaims>
<OutputClaim ClaimTypeReferenceId="isThisAvailable" />
</OutputClaims>
<UseTechnicalProfileForSessionManagement ReferenceId="SM-Noop" />
</TechnicalProfile>
</TechnicalProfiles>
</ClaimsProvider>
And the orchestration step which is the first of the journey :
<OrchestrationStep Order="1" Type="ClaimsExchange">
<ClaimsExchanges>
<ClaimsExchange Id="TEST-CheckIfThisIsAvailable" TechnicalProfileReferenceId="CheckIfThisIsAvailable" />
</ClaimsExchanges>
</OrchestrationStep>
But when I call the user journey, I get this error in Dialog Insight :
The method or operation is not implemented
Note that I also tested putting the transformation in the OutputClaimsTransformations section of my TechnicalProfile without any success.
Here are the last log lines from dialog insight showing that it happens in step 1 :
{
"Kind": "Action",
"Content": "Web.TPEngine.StateMachineHandlers.MoveFirstOrchestrationStepHandler"
}, {
"Kind": "HandlerResult",
"Content": {
"Result": true,
"Statebag": {
"ORCH_CS": {
"c": "2022-11-11T21:17:53.9870141Z",
"k": "ORCH_CS",
"v": "1",
"p": true
}
}
} }, {
"Kind": "Action",
"Content": "Web.TPEngine.StateMachineHandlers.InvokeValidationProfileDirectHandler"
}, {
"Kind": "FatalException",
"Content": {
"Time": "9:17 PM",
"Exception": {
"Kind": "Handled",
"HResult": "80004001",
"Message": "The method or operation is not implemented.",
"Data": {}
}
} } ]
EDIT
I found out that it works when using the authorize enpoint, but I get the error when I use the token endpoint.
To make things perectly clear, the only step in the actual orchestration is to get a ROPC token, for tests in dev environments. That works fine on a call to the token endpoint.
<OrchestrationStep Order="1" Type="ClaimsExchange">
<ClaimsExchanges>
<ClaimsExchange Id="ResourceOwnerFlow" TechnicalProfileReferenceId="ResourceOwnerPasswordCredentials-OAUTH2" />
</ClaimsExchanges>
</OrchestrationStep>

</InputClaims>
<OutputClaims>

</OutputClaims>
<OutputClaimsTransformations>
<OutputClaimsTransformation ReferenceId="CreateSubjectClaimFromObjectID" />
</OutputClaimsTransformations>
<UseTechnicalProfileForSessionManagement ReferenceId="SM-Noop" />
</TechnicalProfile>
But as soon as I try to add an orchestration step before like this, I get an error
<UserJourney Id="ResourceOwnerPasswordCredentials">
<PreserveOriginalAssertion>false</PreserveOriginalAssertion>
<OrchestrationSteps>
<OrchestrationStep Order="1" Type="ClaimsExchange">
<ClaimsExchanges>
<ClaimsExchange Id="TEST-CheckIfThisIsAvailable" TechnicalProfileReferenceId="CheckIfThisIsAvailable" />
</ClaimsExchanges>
</OrchestrationStep>
<OrchestrationStep Order="2" Type="ClaimsExchange">
<ClaimsExchanges>
<ClaimsExchange Id="ResourceOwnerFlow" TechnicalProfileReferenceId="ResourceOwnerPasswordCredentials-OAUTH2" />
</ClaimsExchanges>
</OrchestrationStep>

Answer 1

If you are just setting the claim to a specific value, you could use
<InputClaim ClaimTypeReferenceId="isThisAvailable" DefaultValue="false" AlwaysUseDefaultValue="true" />
