[🐞] serializeQRL: Cannot resolve symbol s_90E3ENLVOAc in null undefined

[codeyash]

Which component is affected?

Qwik Optimizer

Describe the bug

This code works perfectly in Dev mode but failing in Prod mode. Tried all types of middlewares like express, Deno etc

const process_text: QRL<(o: any) => string> = $(
  (o: any): string => `${JSON.stringify(o)}  Hello`
);

const e = {      
    filters: ["groups__name=User"],
     process_text: process_text
}

const data = useStore(e)

Reproduction

Above info should be enough

Steps to reproduce

Bun Dev: works perfectly

Bun Preview : As soon this runs and tried to visit the relevant page which use above store, whole server crashes. Without even calling process_text server crashes. Full crash log https://pastebin.com/TNCsRpDW

Additional Information

How to debug in prod is missing on docs. I have to debug line by line to find what's the problem. Crash logs are not helpful.

[codeyash]

I solved by moving my code from routeLoader$(index/route) to Task$ inside component.

I still consider it as bug in routeLoader$ which failed to collect all required fn for final build.

Right this seems to be an issue with the optimizer. Can you please try reproducing in https://qwik.dev/playground? It should also be failing there, since it does production builds.

I am also getting this error when building:

  '6X0KberS7Oc': [ 's_6X0KberS7Oc', 'q-DttXmm6U.js' ],

  ...
} undefined

@lbensaad that's a different issue and it's likely solved in the upcoming 1.9.1 release

[lbensaad]

@wmertens when v 1.9.1 will be released?

[lbensaad]

The issue still there in v 1.9.1, is there a way to fix it.

[wmertens]

@lbensaad Can you make a minimal reproduction?

[lbensaad]

The issue has disappeared now, thank you @wmertens.

Strange, I'm getting this error when upgrading from v1.5.7 to 1.11.0 when running a preview build.

EDIT

After some debugging, it seems my preview command used --mode ssr, which isnt used on newer versions of qwik for the preview command, seems that could solve it but will only know for sure once I fix the rest of the issues

[gioboa]

Looking at the comments and the issue seems solved. Thanks.
