Very strange, if you search the Peertube channel first (https://tilvids.com/video-channels/thelinuxexperiment_channel in this case), then the video can be fetched without problems.

Strange indeed. Another strange but potentially relevant behaviour:

Searching the peertube channel first and then searching for the video will fetch the video, unless the video has set as a "Language" some language that includes spaces.

For example, attempting to fetch this video will fail regardless: https://bolitoglossa.com/w/eswbeZtw3aD9VAwvpEpFiA

I have tested switching to other languages with and without spaces, and this failure occurs only when there is a space. I also confirmed that it is not because lemmy lacks a particular language in its list.

The error that appears after having fetched the channel for videos set to languages that include spaces is the following:

The sensitivity of the resolve_object action to spaces in the language entry makes me suspect that this is related to the parsing of the response. I will see if I can find something more concrete.

EDIT: This language problem occurs because the languages with spaces are assigned to three letter language codes, instead of two. I found a language with a single-word name for which a three letter code is used: Kotava, 'avk'. This video has been set to Kotava as a language and can therefore not be fetched: https://bolitoglossa.com/w/6bjY6UtxbwBoDPV7hHUi2d
