Corrupted low-code app after concurrent editing actions

Affected versions

From DataMiner 10.2.5/10.3.0 onwards.

Cause

When two users edit the same low-code app at the same time, it can occur that the App.info.json file refers to object IDs that do not exist. This makes it impossible to still edit the app.

Workaround

Avoid concurrent editing actions. If these have occurred and the App.info.json file is corrupted, manually remove the unknown object IDs from the file.

Fix

No fix is available yet.

Description

After a low-code app is edited by two different people at the same time, the edit page no longer loads when users try to edit the app again.
