artwork uploader exited with status: 1 and error: Error while parsing imgur response: error decoding response body: missing field `link` at line 1 column 177
This occurs with some albums. Some work, some don't.
Does it happen always for the same albums or is it completely random?
It appears to be random, I am not sure. Using the python method worked.
I created a new release that should print the whole response imgur gives when parsing fails. Could you upgrade your script to that and report what the response looks like when this error happens. The imgur API docs don't document error cases well so it's more difficult to know how to handle those without seeing them first.
