[BUG] failed: can not get media info: X/Y
Login successful, joined channel, exported JSON, running tdl -n quickstart dl -f result.json, getting the following errors:

Some files are downloaded, but it seems the program is not able to get media info while already downloading a file, so the get info query is only successful for 1 request until the download is started, and then errors on all subsequent requests until the active download is finished.
What types of files do you download? Images or files?
Only files.
Maybe more information is needed, can you try to take a screenshot of what one of the files looks like in desktop client? And mosaic the sensitive information.
