Here are the steps to reproduce the problem I met:

1. Run SQL Server Container for Linux

   docker run -e "ACCEPT_EULA=Y" -e "SA_PASSWORD=Ver7CompleXPW" -p 1433:1433 --name sql1 -d mcr.microsoft.com/mssql/server:2019-latest

2. Deploy ContosoUniversity.dacpac as data-tier application

   sqlpackage /Action:Publish /SourceFile:"ContosoUniversity.dacpac" /TargetDatabaseName:"ContosoUniversity" /TargetServerName:"." /TargetUser:sa /TargetPassword:Ver7CompleXPW /p:RegisterDataTierApplication=true /p:BlockWhenDriftDetected=true  /TargetTrustServerCertificate:true

3. Deploy again using the exact same above command.

   sqlpackage /Action:Publish /SourceFile:"ContosoUniversity.dacpac" /TargetDatabaseName:"ContosoUniversity" /TargetServerName:"." /TargetUser:sa /TargetPassword:Ver7CompleXPW /p:RegisterDataTierApplication=true /p:BlockWhenDriftDetected=true  /TargetTrustServerCertificate:true

   Here is the output:

   Publishing to database 'ContosoUniversity' on server '.'.
   Initializing deployment (Start)
   Initializing deployment (Failed)
   *** Could not deploy package.
   Unable to read data-tier application registration.
   Time elapsed 0:00:10.68
   

4. I'm trying to create a DriftReport

   sqlpackage /Action:DriftReport /TargetDatabaseName:"ContosoUniversity" /TargetServerName:"." /TargetUser:sa /TargetPassword:Ver7CompleXPW /OutputPath:DriftReport.xml

   Here is the output:

   Generating drift report for database 'ContosoUniversity' on server '.'.
   *** Could not generate drift report.
   Unable to read data-tier application registration.
   Time elapsed 0:00:00.64
   

5. If I delete the data-tier application and register it from SSMS. Then the above commands are all works.

6. If I use the following command to publish again.

   sqlpackage /Action:Publish /SourceFile:"ContosoUniversity.dacpac" /TargetDatabaseName:"ContosoUniversity" /TargetServerName:"." /TargetUser:sa /TargetPassword:Ver7CompleXPW /p:RegisterDataTierApplication=true /p:BlockWhenDriftDetected=false

   Note: the /p:BlockWhenDriftDetected is false which means this don't read the data-tier application registration.

7. Then the /Action:DriftReport still showing Unable to read data-tier application registration.* error message.

   sqlpackage /Action:DriftReport /TargetDatabaseName:"ContosoUniversity" /TargetServerName:"." /TargetUser:sa /TargetPassword:Ver7CompleXPW /OutputPath:DriftReport.xml

   logs:

   Generating drift report for database 'ContosoUniversity' on server '.'.
   *** Could not generate drift report.
   Unable to read data-tier application registration.
   Time elapsed 0:00:00.64
   

Is this a bug?
