Also seeing this issue...does anyone have a workaround or fix?

[mjroeleveld]

My workaround was to use env files for single-line secrets.

Are you sure there's no newline in your input file? Most editors append a newline at the end of a line so even if in e.g. VIM you don't see a newline, it's actually there.

[mjroeleveld]

The tests of the kustomize-controller actually check for this newline, too.

I had trouble editing the file properly via every IDE, I then clone my git repo to VS and was finally able to remove the newline
