Error: Invalid inputs given to generate an instance of 'Token'

Version

fastly==4.0.0

What happened

I got an error while trying to list all tokens belonging to a customer.

In order to get started, I used the sample script provided here: https://github.com/fastly/fastly-py/blob/main/docs/TokensApi.md#list_tokens_customer

But when I tested it, I got the following error:

I was expecting to get a list containing all tokens belonging to my customer account.
Am I missing something? Can you folks help me to understand that error?

Any support would be highly appreciated!
Thank you!

Hi @gsbiel

Thanks for raising this issue. Looks like there's a problem with the code-generation process for this API client.

The error is:

fastly.exceptions.ApiValueError: Invalid value for `scope` (global:read global), must be one of ['global', 'purge_select', 'purge_all', 'global:read']

Looking at the documented API https://developer.fastly.com/reference/api/auth-tokens/user/#data-model it seems scope can be assigned a "space-delimited list of authorization scope", which it is in your case (based on the error: it's set to global:read global) but the generated code for the API client thinks that it should be a single value (based on the error: must be one of ['global', 'purge_select', 'purge_all', 'global:read']).

I'll open a ticket internally to track this.

Hi @Integralist
Thank you very much for your support on this :)

I tried to workaround that error by configuring my Fastly API key to have only a single value as scope, but no success.
In that case, I setup only global:read scope, but got another error:
