Describe the bug
When adding an external data source such as MS SQL or PSQL unexpected errors occur.

MS SQL - When adding the data source, selecting no tables or clicking skip crashes the builder. Page needs to be refreshed. When deleting the data source, the builder returns the error "Error deleting datasource"

Postgres - When deleting the data source, the builder returns the error "Error deleting datasource"

To Reproduce
Steps to reproduce the behaviour:

1. Add a new data source - MS SQL or Postgres (have only experimented with these two so far, others may also be affected)
2. Select no tables, or skip fetching tables
3. delete (or attempt to delete) the data source

Expected behaviour
A clear and concise description of what you expected to happen.
