The Nakama Godot SDK unfortunately is not compatible with the Godot 4.0 Stable release. There are multiple pull requests pending on GitHub that fix a lot of these isssues (such as this one, which seems to fix most of the issues), however they all seem to have been ignored so far.
I actually found another bug in the
NakamaHTTPAdapter.gd that I’m not sure if I should make an issue about, which is this line in
if json_error != OK: logger.debug("Unable to parse request %d response. JSON error: %d, response code: %d" % [ id, json.error, response_code ])
json.error should actually be
json_error, otherwise Godot throws an error.
