Long-running processes fail with Error: ENOENT: no such file or directory

[jordanandree]

First off, thanks for this great library!

When setting it up for an existing cypress project, I've noticed that some files that take a while to preprocess will throw an error in the Cypress runner output window:

Error: ENOENT: no such file or directory, stat '/Users/<user>/Library/Application Support/Cypress/cy/production/projects/<project-hash>/bundles/cypress/e2e/<spec>.cy.ts'

After a few minutes of waiting, it seems that Vite builds the file and emits an event for Cypress to rerun, which then it succeeds. I'm wondering if there are some improvements that can be made to the watcher for the preprocessor, but I'm not super familiar with Cypress file preprocessors.

Here is a rough diff for the final return of the process here. I was able to working locally that checks if the ouputFile is ready or otherwise will throw an error. Ideally it would be nice to have Cypress wait longer before outputting anything but I couldn't figure that out:

-    cache[filePath] = outputPath
-    debug("Bundle for file %s cached at %s", filePath, outputPath)
-    return outputPath
+
+    if (fs.existsSync(outputPath)) {
+      cache[filePath] = outputPath
+      debug("Bundle for file %s cached at %s", filePath, outputPath)
+      return outputPath
+    }
+
+    if (shouldWatch) {
+      debug("Bundle not ready while compiling original file %s", filePath)
+      throw Error("Bundle not ready while compiling original file")
+    } else {
+      return filePath
+    }

Hi @jordanandree, thanks for reaching out.
Recently, I experienced the same delay on the first run in one of my projects and it was because of a not-optimized dependency in the app. Obviously, in my case, it wasn't the tests that caused the problem. I'm not sure, but maybe in your case, there is a test utility or some third party that is causing the issue. Can you check to see whether this is true? Or maybe a Vite plugin is causing the issue?

I don't think throwing error is the right way to solve this. I'll try to figure out some way for triggering a rerun when the bundle is ready. And btw, more information about the tests, configuration, etc., or perhaps a reproduction can help me through this.

Hi, thanks for great library like this ! :)

I got same error.
Execute npx cypress open and run e2e test, then Cypress Studio shows the following error.

Error: ENOENT: no such file or directory, stat '/Users/<user>/Library/Application Support/Cypress/cy/production/projects/front-7a0bead4da052e7d0236bfff078df7a5/bundles/cypress/e2e/xxx/xxx.cy.ts

This file exists surely but has extention .ts.js not .ts.

/Users/<user>/Library/Application Support/Cypress/cy/production/projects/front-7a0bead4da052e7d0236bfff078df7a5/bundles/cypress/e2e/xxx/xxx.cy.ts.js

Why and how to fix it ?

snagasawa I am experiencing the exact same problem! I think there is an actual issue with this library but I can't seem to fix it. If anyone knows how to fix this please say

[oren-legit]

@jordanandree @snagasawa Cypress version 10.11 seems to solve this (with Node 17).

[mammadataei]

@jordanandree @snagasawa do you confirm that Cypress@10.11 solves this?

[snagasawa]

@oren-legit @mammadataei
Cypress version 10.11 solve this error, although different issue occurred. Thanks. :)
v11.2 still got error.

[mammadataei]

@snagasawa same error on v11.2?! If so, could you please send me the debug output?
Feel free to open a new issue if you are facing a new error; I'll do my best to resolve it.

I had same error, no output from debug. Then i matched versions, tsconfigs and vite configs to this example repo.
Then i got error:
RollupError: Invalid value for option "output.manualChunks" - this option is not supported for "output.inlineDynamicImports".

after removing this piece of code from my vite.config.ts it started working.

@MartinN3 Can you clarify in what file and what code you removed to get this working?
