You are editing the message with {embed: null}. As the message only has an embed, this removes the embed and there is therefore no content to edit the message with.

If I interpreted the code correctly, you want to update the embed, so use this:

We can use str_count

Eclipse was installed as 'Administrator' and then run 'normally' (as a user).

Reinstalling all as user solved the problem.

Eclipse's error message says "for current branch" (emphasis mine), so presumably it's not willing to take a global repository-wide remote: it wants one specifically for the current branch. If there is only one remote, most likely named origin, presumably this means you should set the current branch's remote setting to origin. If the current branch is zorg that would, on a command line, be git config branch.zorg.remote origin. What commands to use, or clicky boxes to click on, in Eclipse, I cannot say.

This seems like a bug in Eclipse: Git in general will use origin when no remote is configured (e.g., if you run git fetch and the current branch has no configured remote, Git tries to fetch from origin). Since Eclipse is its own thing, it can of course make its own rules, disregarding Git's in little ways like this, or even in major ways.
