The GetCSVHeader API is failing even through the console since 2 days ago.

• Console created a headers.csv file that only contains the string: "There was a problem downloading CSV headers. Please try again."


• API error is: "An error occurred (InternalErrorException) when calling the GetCSVHeader operation (reached max retries: 4): Internal server error."

Is there a workaround or alternative to get this?

First: You should definitely report this to AWS Support, because if it's an outage or a bug they'll be interested in getting it fixed.

However as a workaround, I suspect you could just author it yourself. From the documentation here, the format is fairly transparent:

 "CSVHeader": [
 "name",
 "given_name",
 "family_name",
 "middle_name",
 "nickname",
 "preferred_username",
 "profile",
 "picture",
 "website",
 "email",
 "email_verified",
 "gender",
 "birthdate",
 "zoneinfo",
 "locale",
 "phone_number",
 "phone_number_verified",
 "address",
 "updated_at",
 "cognito:mfa_enabled",
 "cognito:username"
 ],
 "UserPoolId": "USER_POOL_ID"

Specifically, the CSVHeader section is just a list of active attributes in your user pool. The full list of built-in attributes can be found here, and any you've created will be in the form custom:ATTRIBUTE_NAME.
