JWT encoding is not working

Description

API invocation fails when enabling the backend JWT.

Steps to Reproduce

Get an APIM 4.1 pack and update to level 79 or the latest.
Enable backend JWT with the below configurations.

[apim.jwt] enable = true header = "X-JWT-Assertion" enable_user_claims = true Furthermore add the below set of application attributes as well.

[[apim.devportal.application_attributes]] required=true hidden=false default="Yes" name="Sandbox access required ?" description="Does this Application require access to APIs in the Sandbox environment ? (Yes or No)"

[[apim.devportal.application_attributes]] required = true hidden = false name = "date_Review Date" description = "What date should API access terminate or be reviewed?"

[[apim.devportal.application_attributes]] required = true hidden = false name = "date_Start Date" description = "test"

[[apim.devportal.application_attributes]] required=true hidden=false default="Yes" name="Production access required ?" description="test"

[[apim.devportal.application_attributes]] required=false hidden=false name="Sponsor's name" description="Person responsible for the project this Application represents"

[[apim.devportal.application_attributes]] required=false hidden=false name="Usage description" description="What is the purpose/service/project/product of the Application requiring API access ?"

Login to the carbon management console and create a user by providing the username as “admin.abc” Go to the devportal and create a new application, subscribe API, generate keys and invoke the API. The first invocation will work, but you’ll observe the same error from the second invocation onwards. As per these observations, the issue occurs even without a custom JWT generator
