WebGL Build Failure when updated to 5.4

This worked fine in 5.3.5 but started occurring now 5.4. It appears to fail to do compression during the build? The result build still actually works (not sure what the implication of this failure would be) but forces the build to bail before my post build processor scripts run. That's unfortunate.

My post processor copies .js files over into a created js folder and zips the js folder with the Release/Development folder. This error appears to occur if that zip file exists. I'd be happy to delete the zip file as part of a pre build processor but the attribute doesn't exist

Error

I'm having the exact same issue, I tried using brotli compression now testing with gzip

 

This is what I get with gzip and brotli

EDIT: Oops sorry I guess this is for Beta 5.5 thread.

 

@jonas-echterhoff I'll open up a bug shortly. A little bit more information, the error has nothing to do with my own post processor and just if there are already build files there. The short, if I build to a directory with existing files then it errors otherwise it works just fine.

 

Opened up a bug. Case number is 828005.

 

Unfortunately it is still reproducing in both 5.4.0p1 and 5.4.0p3

 

I'm also seeing this in 5.4.0f3.

 

UI

 

I'm having the same issue. I don't use any sort of build script, just a build straight from Unity. Here's the error:

 

Yep, that's fixed. Thanks a lot.
