Hi Team,
Hope you are doing well.
Actually I am getting error while publishing on BC Cloud Sandbox after getting WAVE 1 2020 Update.
It says
The request for path /v2.0/sandbox/dev/apps?SchemaUpdateMode=synchronize&DependencyPublishingOption=default failed with code UnprocessableEntity. Reason: ForceHandleTrackingEvent failed to acquire a lock
But it is allowing to install Manually from Extension Management .
