Describe the bug
On the Design / Create new screen page, after selecting Table or Form, no datasources are listed.

To Reproduce

1. Create a new app
2. Add a REST API datasource, with a query for GET https://cdn.githubraw.com/Juriy/swapi/refs/heads/master/resources/fixtures/films.json
3. In the query, add a transformer return data.map(film => film.fields)
4. Save the query
5. In the Design view, select Table

Expected behavior
On the Autogenerated screens modal, after the text Select which datasources you would like to use to create your screens there is a way to select the REST API datasource.

Screenshots
Observed: no option to select a datasource.

Desktop:

• OS: macOS 15.1.1
• Browser: Safari 18.1.1

BUDI-8928 Datasource not listed when adding autogenerated screens

Hey @hilton - I believe this is working as intended.

Looking at the code here: https://github.com/Budibase/budibase/blob/master/packages/builder/src/pages/builder/app/%5Bapplication%5D/design/_components/NewScreen/DatasourceModal.svelte we can see that rest entities are excluded as part of the getDatasources function on line 44.

@mikesealey Thank for for the quick response. That is… a surprising design decision, given that the conventional meaning of datasource is that it’s an abstraction that you can use interchangeably with other data sources. I guess this is a UX issue then, as neither UI nor docs made me aware of the limitation.
