@DantasB thanks, now there are a few mypy validation error -> https://github.com/datahub-project/datahub/runs/5984956469?check_suite_focus=true#step:6:1126

src/datahub/ingestion/source/redash.py:503: error: Argument 1 to "_get_database_name_based_on_datasource" of "RedashSource" has incompatible type "Optional[Any]"; expected "Dict[Any, Any]"
src/datahub/ingestion/source/redash.py:552: error: Argument 1 to "allowed" of "AllowDenyPattern" has incompatible type "Optional[str]"; expected "str"
src/datahub/ingestion/source/redash.py:674: error: Argument 1 to "allowed" of "AllowDenyPattern" has incompatible type "Optional[str]"; expected "str"

Please, can you fix those as well? Let me know if you need any help.

Hey @treff7es sorry for taking too long to fix this linter, it's just because the college activities return back recently so it's beeing quite hard to handle a lot of things hahaha! I'll try to fix that today, if it's beeing to hard i'll ask you for help, ok? Thanks!

[DantasB]

@treff7es now i think that mypy will not fail again.

We are closing the PR due to dormancy.

We've not heard this feature request for the Redash source since this was opened.

Thanks for the awesome contribution @DantasB! Please reach out if you'd like to start up this thread again, and we'll work with you to figure it out.

Cheers John
