Login type "inherit" fails with error "Cannot bind argument to parameter 'String' because it is null"

I am updating an existing deployment using SPN to use the service connection identity instead, using "loginType: Inherit". This fails with the error "Cannot bind argument to parameter 'String' because it is null". In my case, I am using an ADO managed identity service connection.

ADO task output:

Working YAML task definition using SPN:

  - task: deploy-aas-db@1
    displayName: 'GeneralLedger: Deploy model'
    inputs:
      # Azure DevOps connection info
      connectedServiceNameSelector: connectedServiceNameARM
      connectedServiceNameARM: ${{ parameters.ServiceConnectionName }}
      # Analysis Services connection info
      aasServer: ${{ parameters.ServerURL }}
      databaseName: ${{ parameters.DatabaseName }}
      # Authentication type
      loginType: SPN
      # Type-specific authentication details
      appId: ${{ parameters.SpnId }}
      appKey: ${{ parameters.SpnPassword }}
      tenantId: ${{ parameters.TenantId }}
      # Model deployment info
      pathToModel: ${{ parameters.BuildArtifactPath }}/${{ parameters.PathToModel }}
      partitionDeployment: retainpartitions
      roleDeployment: deployrolesretainmembers
      # Source connection info
      connectionType: ${{ parameters.SourceConnectionType }}
      sourceSQLDatabase: ${{ parameters.SourceSqlDatabaseName }}
      sourceSQLPassword: ${{ parameters.SourceSqlPassword }}
      sourceSQLServer: ${{ parameters.SourceSqlServerFqdn }}
      sourceSQLUsername: ${{ parameters.SourceSqlUserName }}

Failing task definition using "inherit". The only difference is using "loginType: Inherit" and leaving off the appId, 'appKey, andtenantId` parameters, although I did also try leaving those parameters in with both real values and blanks.
