What does it mean if we cannot pick tickets in Slack and there is a restricted_action error in the logs?
If there is a restricted_action error in the logs, that means there is a team preference that prevents the authenticated user from creating channels. Please check if you have updated the create channel setting for your Slack workspace recently.
You could follow the steps below to change all the settings back to the default setting.
1. In your Slack app, select your workspace name at the top left corner. Under Settings & administration, select Workspace settings from the drop-down list.
2. Go to the Permissions tab on the top.
3. Scroll down to Channel Management and choose Expand.
4. Please change all the settings back to the default settings.
5. Save your settings.
