Profile 'login-NonInteractive' in policy 'B2C_1A_signup_signin' in tenant 'tenant.onmicrosoft.com' does not contain the required cryptographic key 'client_secret'.

Question

I am trying to set up Local account sign-in using B2C but I keep geting this error. Signup works without a problem and returns an access_token once a user completes the flow but using the same credentials to login fails. I have tried using a default sign in user flow and it works with the same credentials. What am I missing? Or what am I supposed to use for the client_secret?

Error:
Profile 'login-NonInteractive' in policy 'B2C_1A_signup_signin' in tenant 'tenant.onmicrosoft.com' does not contain the required cryptographic key 'client_secret'.

Hi @Thulani Tembo · Thank you for reaching out.

• Make sure you registered IdentityExperienceFramework and ProxyIdentityExperienceFramework as explained here: https://learn.microsoft.com/en-us/azure/active-directory-b2c/tutorial-create-user-flows?pivots=b2c-custom-policy#register-identity-experience-framework-applications and configure the ClientID (AppID) of these applications under login-NonInteractive technical profile within TrustFrameworkExtension.xml file.

       <TechnicalProfile Id="login-NonInteractive">  
         <Metadata>  
           <Item Key="client_id">ProxyIdentityExperienceFrameworkAppId</Item>  
           <Item Key="IdTokenAudience">IdentityExperienceFrameworkAppId</Item>  
         </Metadata>  
         <InputClaims>  
           <InputClaim ClaimTypeReferenceId="client_id" DefaultValue="ProxyIdentityExperienceFrameworkAppId" />  
           <InputClaim ClaimTypeReferenceId="resource_id" PartnerClaimType="resource" DefaultValue="IdentityExperienceFrameworkAppId" />  
         </InputClaims>  
       </TechnicalProfile>  
  

• Also make sure you have added signing and encryption keys as mentioned here: https://learn.microsoft.com/en-us/azure/active-directory-b2c/tutorial-create-user-flows?pivots=b2c-custom-policy#add-signing-and-encryption-keys
