Error while executing Bun script: missing sourcemaps

After updating to the latest Windmill Docker image, I started getting this error when running a specific Bun script:

ExecutionErr: ExitCode: 1, last log lines:

I tried wiping everything under /tmp/windmill/cache/bun and /tmp/windmill/cache_nomount/bun{,tar} and redeploying the script, but I still get the same error.

use //nobundling at the top it has nothing to do with sourcemaps we just use pre-bundling now which in some cases fail which you can disable with //nobundling

oh, I see this did indeed fix it it does appear to be working just fine in some cases, not sure what's "special" about this particular script

rubenf•4mo ago

it's a bun bundler issue, if you isolate it, please report it to bun project and windmill will eventually pick up the fix

invakid404OP•4mo ago

yeah, figured unfortunately, it's a script that does quite a lot and has a lot of dependencies, so it'd be tough to pinpoint exactly what's causing it

rubenf•4mo ago

the more it does, the more you will benefit from bundling 🙂

I'll spend some time with it later to try and figure out what goes wrong nobundling will do for now thanks!
