From a UX POV, probably not.

If this is a security complaint, well, its less exposed information (a strict subset) than if your app was open source, so I don't see it as particularly a problem.

Actually it's not a subset. Even if the app is open source, what you gain from this error is: username, installation path, resource limits. All of those add something you don't know from the code itself. All can be useful when trying (respectively) injections / bruteforce auth, path traversal / secrets access, denial of service.

Also line numbers can help you identify the deployed version.

Also optional table prefixes which are deployment-specific.

You're right, I was wrong; leaving the grandparent post just for context for your response, otherwise I'd delete it.

Information leakage is considered a security vulnerability. https://www.owasp.org/index.php/Information_Leakage
