I'm unable to reproduce this error at the moment, but I suspect it's already fixed in the upcoming gem version 0.33.0 (currently in the castwide/solargraph repo's closure branch). Based on the stack trace, I think it's an issue with how literal values (explicit strings, numbers, arrays, or hashes) get assigned to variable types. The new process eliminates a redundant step where this error likely occurred.

If you can provide a reproducible example, I can try to confirm. If not, we can see if it still happens after 0.33.0.

Thank you! I've just checked out 0.33.0 and it works. Looking forward to use released version instead of the one from branch 😃
