Thanks for the migration guides. Actually, I found the issue. This was happening for the Cloudflare cache. I purged the cache and it is working fine now.

I can reproduce this, ill try some of the above. I'm using cloudflare too but this usually isn't an issue in other node projects, are both file names the same in the output of the file between versions, is this why? @derrickmehaffy

That could be part of the cause, CloudFlare didn't update it's cache or wasn't aware it needed to bust it's cache.

I'm facing the same problem, I tried all of them but it didn't work. With google chrome and edge web browser, white screen occurs, safari also enters smoothly.

I am facing the same issue in production. If I purge the cache, it works but only for one visit. After one visit, the cache is broken again and I have to purge it again.

@sultanfendonus please reopen this issue as purging cache only works temporarily.

Thanks. I reopened it. Hopefully Strapi team will solve this soon.

[derrickmehaffy]

We need more information to reproduce this. @kentnek can you please open a new issue, link to this one, and provide more information that helps with reproduction because at this stage I have a feeling it's an environment issue, not an actual bug.

Having this same issue... It's trying to do 1.toFixed which is causing the issue.

Edit: This is an issue with Cloudflare changing it from 1 .toFixed to 1.toFixed.

I had this same issue, purging the cache on Cloudflare would only solve it temporarily.

Solved it by disabling the minify options on Cloudflare. It's working now!
