Support for Auth0 credential provider when using the request_access_token decorator and for Identity.get_token #109
Description
Is your feature request related to a problem? Please describe.
In order to get an access_token from Auth0, you need to pass an additional audience parameter in the request.
Using boto3 directly this can be accomplished with:
workload_access_token=BedrockAgentCoreContext.get_workload_access_token()
resp = acr.get_resource_oauth2_token(
workloadIdentityToken=workload_access_token, resourceCredentialProviderName='resource-provider-oauth-gateway',
scopes=[],
customParameters={'audience': '<the_audience_of_the_API>'},
oauth2Flow='M2M')
print(resp['access_token'])
The request_access_token decorator does not support passing that parameter and the request fails since the returned token is an opaque token and not a valid JWT.
raise error_class(parsed_response, operation_name)
botocore.errorfactory.ValidationException: An error occurred (ValidationException) when calling the GetResourceOauth2Token operation: Error parsing ClientCredentials response
Describe the solution you'd like
Add a customParameters parameter to the decorator
Describe alternatives you've considered
One can use the boto3 API directly, but introduces friction to the developer experience
