Next.js SSR handler crash

[mrcportillo]

Hi, our netlify project is failing when accessing a “second level” URL, this means that https://domain.com/something works fine, but https://domain.com/something/something-id fails, it does it for all the routes and it started without changes in our codebase, so I believe it might be related to SSR and how netlify serves the page.
The error that is displayed in thee browser is:

and the logs of SSR handler are:

Runtime.ImportModuleError

Thu build is made with node v14.21.2 and npm v 6.11.3

I was able to fix this by updating node/npm versions to 16.19.0 and 8.19.3. Even though the NODE_VERSION and the NPM_VERSION env variables were set with the values mentioned before, I discovered that the functions are using a much higher version of node, I assume that was the problem.

In the environment variables setup of the building is possible to set up a version for functions, I think that is not working, otherwise, this issue would never have taken place.
