ParserError: Expected '=>' but got identifier what is wrong with this '=>'.#support!

You are using a compiler version older than 0.8.18, which is the first version to allow named parameters in mapping types.

Also, please post the relevant code as plain text (no screenshots or images).

I get these error when I compile 0.8.20 version...

Error HH600: Compilation failed

First of all, are we supposed to know what this contract is???

Second, now that you've solved the original problem, you may as well mark your question 'Solved', and post the new problem in a new question.

Third - once again - please post ALL the relevant information and ONLY the relevant information; for example - source code, error messages, project configuration, etc.

Fourth - once again - please post everything in plain (copy-pastable) text; no screenshots, no images and no links other than links to GitHub.
