You don't have a main method, and you don't specify what “the above
method” is.

I assume you mean “… calling the ‘GenAccessToken’ function” (which is
not a method of anything, in the code you showed). But maybe you mean
something different?

Can you show an example Python interactive session which:

* Imports your module.

* Calls the function.

* Demonstrates the behaviour that is confusing you.

You may not realise (I assume you are not a native English speaker),
that is *very* demanding and rude. We are a community of volunteers
here, asking for a response “ASAP” is making demands you are not in a
position to make.
