Hi AlexIV,
Sorry about the delayed reply here
The fact that the error message is extremely unhelpful is entirely my fault. When I added telemetry a while back, I had to ensure no sensitive information could be sent back to my database, and I simply forgot to re-add so the user can see these API requests themselves locally.
I will release a 0.5.6-alpha.1 later today, which will give you more information about why your request fails.
Sorry for the inconvenience.
