Error when building app

[MaximeCoteL]

Cannot read properties of undefined (reading 'D:\Documents\transport_en_commun\RailFansMap.pnp.cjs

Didn't work on my fantasy lines in a while and haven't changed anything, and now I get yarn errors when starting... Any ideas what the error mean ? I tried changing versions in package.json but wasn't able to fix it.

Everything is building normally on my end (with the same version of yarn) but here are a few things to check first:

1. What version of Node are you using?
2. You could try deleting the .pnp.cjs file and let yarn regenerate the file.
3. Have you added any new dependencies in your fork that aren't in the main project?

1. I am using node v18.18.2
2. I tried and it didn't fix anything.
3. I have not !

Finally, I'm not certain if I changed anything compared to last time I tried to start it, but now it starts, but when I ctrl + click on http://localhost:8080/ to open it, I get that last line ''wait until bundle finished'' but it's stuck there..
