fix: searchAssets and searchMetadata return 400 #309
Description
Since last week i noticed an issue with the Connection instance.
When trying to fetch assets and metadata, the message received was 'HTTP Error: Requested page not reachable'.
So out of curiosity i tried with a different HTTP client (axios) and with the browser and both were getting valid responses.
The issue is probably around this file, but i didn't have time to investigate.
