Question

Hellow all,I am trying to get a Access token using the password grant type ina POST request from Azure AD B2C, but when I sent it I am getting the below error

"error": "server_error", "error_description": "AADB2C90108: The orchestration step '1' does not specify a CpimIssuerTechnicalProfileReferenceId when one was expected.\r\nCorrelation ID: .............\r\n"

I have tried with other authentication types like client credintials which is not working azure ad b2c but getting below error

"error": "unsupported_grant_type",
"error_description": "AADB2C90086: The supplied grant_type [client_credentials] is not supported.\r\nCorrelation ID:

please help

Answer 1

The usual reason you get this is that it's missing eg

<OrchestrationStep Order="3" Type="SendClaims" CpimIssuerTechnicalProfileReferenceId="JwtIssuer" />

Are you using a custom policy? What type of policy are you using?

As the error message says, "client credentials" is not yet supported in B2C.
