@jamesozzie
from the error response I see it's because the keyinvalid.
Can you please try reset site kit, and try to activate PSI module again, and ensure you copy the correct API Key?

[jamesozzie]

Thanks @ivankristianto. Thanks for the update. It's working fine when I reset, I never made any changes or set restrictions on that project in GCP. I copied and pasted the API directly. But if it arises again I will report.

@ivankristianto. I have a video here where you can see the issue again, not just on a subdomain. Would there be something else causing this? Even after resetting Site Kit and repeating the process using incognito mode:

@jamesozzie can you check for excess spaces in the api key?
related to this issue #81

[jamesozzie]

@ivankristianto While there appears to be an additional space in the generated API key this is not the cause of the problem, as the copied API key does not include this space (copied directly via the copy button or copied via selecting the text, copying & pasting). This is not the root cause of this issue.

@jamesozzie
If it is a correct API key, the other possible way is you might have API restriction set for your API.
Can you check it in GCP dashboard?
What do you have in that key setting? You can check it with this link: https://console.cloud.google.com/apis/credentials

ANd here is the screenshot look like

[jamesozzie]

@ivankristianto There are no restrictions set, see below:

Let's re-test this after #81 is fixed.
