Bug Report forhttps://neetcode.io/problems/anagram-groups

Please describe the bug below and include any steps to reproduce the bug or screenshots if possible.

I noticed that my solution didnt even get properly tested. I only got the error "Solution is not defined". I dont really know how I got the buf or how to reproduce it, but I can show the code that threw the error:

testing to just return the solution to one test case:

error message:

compelte code:

return solution
