Hey everybody, I feel like I've gotten this error before but forget how I resolved it. The bundle causing the error is the Extension Management bundle. I have tried to reactivate with no extensions to see if that resolves the problem, and I get this same error. Thoughts?

I've seen previous people having this issue and I think it can be fixed by updating the developer tools

updating the extension manager bundle, not the local tools.

^^^ Thanks Pablo and Greg, I will try that. Being a managed bundle, I'm not confident that I can manually update, but I can still try.

If it’s a TestDrive or Sandbox you can. Prod you cannot.

That fixed it, thanks guys!

I am using a training demo account but I am unable to upgrade the bundle. 😫
