Since activation of the Boards plugin on a Mattermost 7.4 server I get multipe of these errors.
error [2022-11-01 09:20:00.404 +01:00] Error notifying subscribers caller=“app/plugin_api.go:974” plugin_id=focalboard error=““could not get board & card for block c1moax95d17dzzpkfdwic8ra5ao: sql: no rows in result set””
This message usually just means that the system tried to find data for a card which is not there and since this is your first use of Boards, this behaviour is actually expected since you do not have any cards (although the error message is irritating).
Can you confirm that these messages are not just being logged but are also causing problems in the boards plugin for you, like error messages in the GUI, broken functionality, etc.?
I can’t tell as I do not use the boards. I’m just the site admin. Those errors are really irritating. Better I stop reading the logfile with all its false positives.
Well, this message actually just means that the system tried to notify users about a card that does not exist anymore. This could be a race condition or something that needs to be fixed, that’s why I’m asking if this error message is still appearing or impacting your users.
Boards is a pretty new plugin in the Mattermost ecosystem and is under heavy development at the moment, which is why some irrelevant error messages slip through to the logs.
