Internal Server Error, NextJS, Pages
Hi, I come back to you with the same error that randomly reappears with me, once on one computer it works, once on another, and now not at all.
To the point, when I upload my project in NextJS to Cloudflare Pages, everything is ok, there is no error, the page is deployed successfully, but when I go to the link the error “Internal Server Error” appears. I have tried the solutions that have already appeared on the forum, but nothing helps. The best thing is that I have not modified the code in any way for the last time and despite this, with the previous uploud everything was ok.
After firing in terminal: wrangler pages deployment tail.... it receives this error:
GET https://dev.foca.plgbc.org.pl/ - Ok @ 3/24/2025, 5:27:31 PM
(error) TypeError: Cannot read properties of undefined (reading 'navigator')
Any ideas, anyone had a similar problem? Please help, because I already have a delay in the project because of this and I have no idea how to fix it
wrangler version: 3.61.0 (i tested on 3.61.0 and 4.4.0)
