   = note: this error originates in the macro `include_str` (in Nightly builds, run with -Z macro-backtrace for more info)

For some reason the dist folder is not properly copied to assets_tmp.

I'd assume this is a problem with build.rs, but I fail to see what is going wrong.

If I run earthly -i --org ontola --sat henk -P --push +docker-all --tags="latest,v0.37.0", and try to find out where the files are, I notice that the assets_tmp folder is missing - even after the "Could not find ./assets_tmp , copying from ../browser/data-browser/distwarning was printed. I also see that thedist` folder is there and has the files, so it's not as if it's copying an empty folder or something.

I tried running cargo build on the same machine, and that seems to run just fine. Could it be that cross does not properly copy the files? Or maybe it moves things?

One solution is to manually copy the js assets to the right dir.
