Twitter: “Error 500”

Also Youtube forms a problem. I received this email:

Thanks for your patience while we reviewed your project.
To continue with the verification process, you need to update your project OneAll-Site-763096-42 (id: oneall-site-763096-42) to comply with our requirements.
Domain Verification
Please verify the ownership of the following domain(s):
? oneall.com
Go to the Search Console to complete the domain verification process. The account you use must be either a Project Owner or a Project Editor on OneAll-Site-763096-42 (id: oneall-site-763096-42).
If the listed domain(s) are not required for the project, please remove them from the authorized domains section of your OAuth Consent Screen in Google Cloud Console.
Please note: The project you are seeing is your own.
When you’ve made these updates to your project, please reply to this email to confirm that you’re now in compliance.
If you have any other questions, you can read the OAuth Application Verification FAQ or reply directly to this email.

I can’t verify ownership because oneall.com is not my domain but according to your tutorial page I have to add oneall.com

Hello,

the issue with Twitter has already been fixed. The problem with Youtube is likely due to a misconfiguration of the Youtube app. Could you please open a support ticket in your OneAll account? This allows us to have all the required information to give you an answer.

Best Regards,

Just downloaded v5.7 and I’m still getting the same 500 error as above.

What fixed this for me was having Elevated access in Twitter.
