ALOpsAppSource with apply_offering_version_filter: Cannot index into a null array Error

[DanielGoehler]

Describe the bug
Since last Friday afternoon, we have been receiving an error message when publishing a new release to AppSource. We are not sure what is causing the issue. The output indicates that only one Business Central offering is found. Could you please take a look and help us determine whether this is an API or ALOps issue?

the used yaml
please provide the yaml that you used. It helps you put the yaml like this:

steps:
- task: ALOpsAppSource@1
  displayName: 'ALOps AppSource'
  inputs:
    azure_tenant_id: '$(TenantID)'
    azure_app_client_id: '$(AppSourceClientId)'
    azure_app_client_secret: '$(AppSourceClientSecret)'
    apply_offering_version_filter: true
    autopromote: true
    offering_name_filter_array: 'Some App'
    pwsh: true

the output
Also the complete output is necessary for us to see what is going on. Also use backtics:

There IS something wrong with the PartnerCenter API - I contacted Microsoft about it.

[DanielGoehler]

BCCH has the same Problem: microsoft/navcontainerhelper#4090

[waldo1001]

Since Microsoft is too slow in providing a workaround, we investigated and found our own.

[v1.474.10523]

In a nutshell:
ALOps will detect is the PartnerCenter API is bugged, if so, automatically fall back to the Graph-API for retrieving the products.
Why like this: because the API is described to be the one that should be used, but the phased out Graph seems the one that still works..
