User with Node-RED Dashboard UI permission prevents other users from making requests to PAC Control REST APIs

Applies To:

Firmware for the following groov EPICs:

GRV-EPIC-PR1
GRV-EPIC-PR2

Versions Affected:

3.3.0 to 3.5.1

Resolved In Version:

3.6.0

Symptoms:

You may experience this issue if you see the following message while using the PAC Control REST API:

"PAC response error: -401. Unable to authorize transaction. User data temporarily unavailable. ERROR CODE: -401"

This message can be caused by an invalid API key; however, it can also be caused by having any users with the Node-RED Dashboard UI permission on your groov EPIC processor. To determine if you are experiencing this issue, check the PAC Control REST API logs for an error message similar to this one:

ERROR [2023-08-30 17:32:37,215] [main] com.opto22.nxtio.api.rest.pac.controller.security.PermissionManager: Failed to initialize user cache for permissions. ! java.lang.IllegalArgumentException: No enum constant com.opto22.nxtio.api.rest.auth.model.permission.NodeRedPermission.DASHBOARD

Workaround:

For any user assigned the Node-RED Dashboard UI permission, do one of the following:

Increase the permission level to Node-RED Editor.
Decrease the permission level to None.
Delete the user.
