ERR_STRING_TOO_LONG Cannot create a string longer than 0x3fffffe7 characters

Unity Engine

Hi folk,

I got this error message while trying to publish a package larger than 1GB to our local NPM registry. Looks like a Nodejs issue but I hope the Unity community should have the experience with it. Guessing a lof of project will create as large packages with graphical assets.

Thanks in advance!

Hi @Gunvald ,

You are right. This is a NodeJS/npm issue. As long as we rely on it to publish packages, we will have to cope with this limitation. NodeJS offers a configuration to increase the string buffer size limit. If you have Node 8.x or greater installed, you can try set the env var NODE_OPTIONS=--max_old_space_size=4096.

I haven’t tried this myself. So, if you can, let us know if it works!

Regards,

Pascal

Hi Pascal,

I have tried increasing the max_old_space_size, which is solution for another type of error indeed.
FATAL ERROR: invalid array length Allocation failed - JavaScript heap out of memory.

So far, I have to split up the large package into smaller pieces as a workaround. Really hope the Unity editor built-in solution will work soon, with authentication.

Thanks!
