Hello, everyone! I'm new to Datahub Project. I made a setup for a POC a few days ago and today I'm trying to ingest metadata from Metabase. Unfortunately, I'm getting some errors. Everything is ok about permissions and access to Metabase API (I checked by me with a python script). But, before metadata ingestion ends, I get this error below:

I made some searches trying to discover the reason for these errors. My first guess was the API request rate limit, but I found in the documentation that just login requests have rate limits (see here). My second try was to search for the error on the internet and I found not so similar situation but with the same error (see here). It could be possible that Metabase has a security control for User-Agent headers? The user created for this POC is receiving this email every time I try to ingest the metadata from Metabase: Does someone have some idea what I could probably be doing wrong? Thanks for your attention!

Hi @gentle-camera-33498! Gentle reminder to please post large blocks of code/stacktrace in threads - it’s a MASSIVE help for the Core Team to keep track of all open threads across our support channels! teamwork I’ll escalate this one with the team today so we can get you some direction 🙂

Ops! Ok, Maggie! I think I found the problem. I will make local tests to prove the idea. If works, I can create a Pull Request or pass the information to someone to fix.

That would be amazing!!
