I'm able to download the symbols and build the app for Version: US Business Central 20.0 (Platform 20.0.37114.38150 + Application 20.0.37253.38230) - OnPrem.
But, when I'm trying to publish the app from Visual Studio Code, I'm getting the below error,
The request for path /BC200/dev/apps?tenant=default&SchemaUpdateMode=synchronize&DependencyPublishingOption=default failed with code UnprocessableEntity. Reason: An unexpected error occurred after a database command was cancelled.
