AAD B2C returned "AADB2C90090: The provided JWE is not a valid 5 segment token." when calling token API

Question

I am working a POC to verify the migration of our Signup & Signup flow to Azure AD B2C. I have successfully called the API authorize to get the access token and id token. Then I tried to call /token to refresh the token according to document , however I got the error message below.

AADB2C90090: The provided JWE is not a valid 5 segment token.\r\nCorrelation ID: ae943eb7-9290-4fd5-aeac-d56411d803c7\r\nTimestamp: 2022-10-26 07:13:40Z\r\n

Following is the url I used to get access token in Browser.

GET https://{tenant}.b2clogin.com/{tenant}.onmicrosoft.com/oauth2/v2.0/authorize?p=B2C_1_signupsignin1&client_id=7adbb5f8-17d2-4dfa-94cd-5ab1cbc9f425&nonce=defaultNonce&redirect_uri=https://jwt.ms&scope=openid offline_access&response_type=code+id_token&prompt=login

Following is the screenshot I used to call token API in Postman.

I tried to search the error message but only get two discussion threads in Stackoverflow, however no useful info found.

Answer 1

I tried to reproduce the same in my environment and got the same error as below:

To generate the access token, ID token and code in the browser I used the below parameters:

GET https://Tenant.b2clogin.com/Tenant.onmicrosoft.com/B2C_1_testuserflow/oauth2/v2.0/authorize?
client_id=37cd7fca-ea8f-4300-XXXX-XXXXXXXXXX
&response_type=code+id_token
&redirect_uri=https://jwt.ms
&response_mode=fragment
&scope=openid
&state=12345

The error usually occurs if you pass invalid code value. To resolve the error, make sure to copy only the code value not with id token.

I am able to call /token to refresh the token successfully like below:
