CLI is throwing Exception The key {'Id'} cannot be added to keyless type '<TableName>(Dictionary<string, object>)' although I am excluding all tables

I wanted only few stored procs so I marked all (tables, functions, views and SPs) with filter: “exclusionWildcard”: “*” and then added [“exclude”: false] to the stored procs I wanted to reverse engineer. I get the following error complaining about this table <Table_name_in_my_DB> although I am excluding all tables. May be I am missing something here. I checked SQL and that table did not have a PK constraint. I could not do anything since I don’t have enough permissions to Alter the table and see if this solves the issue.

@xheox yeah, maybe it should be skipping all tables and views, but currently it is not happening, as stored procs are not supported by the built-in scaffolding.

I think it might be an issue to skip it, as the DbContext will not be generated then. Maybe you can opt-in to scaffold a single table as a workaround by setting exclude: false for a single (dummy) table?

I suggest installing and try to run “dotnet ef dbcontext scaffold”
