Getting 'import/export' error when running tests through Docker

[jaseauce]

Hello, I am trying to run Cypress (TypeScript) using docker-compose but getting this error - ParseError: 'import' and 'export' may appear only with 'sourceType: module' . In tsconfig, I have already mentioned to use module as commonjs but it doesn't seem to be working.

This happens when trying to import a class to the spec file. Note: this works fine when running tests through npx cypress run

I have created a reproducible example here -

Seems like the image didn't have typescript installed. So I built a custom image with typescript and passed that to Docker compose and now it seems to be working.
