0056256: Vite: "Failed to fetch dynamically imported module" error when executing Cypress tests

Description

Some instances have been observed where the pos2 and try-pos2 tabs fail in the Cypress job due to a random error related with a fetch failure that occurs while reloading the page between tests, which may be related with Vite implementation.

The error message is (notice screenshot)

"Failed to fetch dynamically imported module: <url>"

Following this failure, the subsequent test recovers after the page reloads. This behavior occurs sporadically, and no discernible patterns have been identified.

Here some interesting links related to this behavior:

https://github.com/vitejs/vite/issues/11804 [^]
https://github.com/cypress-io/cypress/issues/25913 [^]
https://stackoverflow.com/questions/69300341/typeerror-failed-to-fetch-dynamically-imported-module-on-vue-vite-vanilla-set [^]

This behavior has been observed not only with Cypress, but also manually, but the steps are not clear enough to define them.

Steps To Reproduce

Steps to reproduce it with Cypress
- Launch a pos2 or try-pos2 job and it may fail due this error.

Proposed Solution

Review why this behavior is happening, maybe a workaround from Vite or Cypress part should be applied.

(0174847) cberner (developer) 2025-01-29 12:00 edited on: 2025-01-29 12:00	There seems to be an open issue in cypress related with this error(as already mentioned in the description): https://github.com/cypress-io/cypress/issues/25913 [^] I think it makes sense to try some of the workarounds proposed there, but most of them do not look easy to implement. I expect the effort to apply them and fix this to be medium-high.
