I have failing tests right now due to a tenant schema issue where a table is not being found in the public schema, which is the wrong schema to look in. That issue has nothing to do with LSP, but that issue has caused a problem for the formatter as seen above, and it is causing an error that it shouldn't. The case of nil should be handled without an exception.
If I run bin/rspec in a terminal, the failing tests give this error without separate exceptions:
ActiveRecord::StatementInvalid:
PG::UndefinedTable: ERROR: relation "optum_lab_orders" does not exist
LINE 1: UPDATE "optum_lab_orders" SET "optum_lab_order_id" = $1 WHER...
^
So that's the real error that the rspec_formatter should be surfacing in the test failures without a backtrace, and that's what running rspec directly shows. My desired outcome is that the formatter output match rspec's output.
You might be able to reproduce the issue by running a migration for a table, creating the model, writing tests for that model, and then manually deleting that table from the database. That might produce similar behavior. I have not tried to reproduce the situation artificially.
