We’ve decided to update future 4.x.x versions to have parity with the old versions of the provider that only used the SDK to structure the code. When 5.0.0 comes around we’ll remove the ability to set provider arguments as “” and have them ignored by the code in favour of ENVs/ADC/etc.
So, I’ll leave this issue open until the provider config logic has been updated to allow
credentials=""(and the same for other string type arguments).I’ll reopen for more investigation but, just to manage expectations, I can’t look into this until next week earliest. Hopefully that isn’t an issue as there’s the workaround you described!
To be clear, when I constrained the provider version to 4.59.0, I was able to run a plan without any other changes.
