Question: Development build with debugging module

Description

Whenever I'm replacing production prebid with unminified/development build of prebid (using resource override) and using __pbjs_debugging__ in session storage, I get this error:

Any idea what might be happening?

I'm building the full version like this: gulp build-bundle-dev --modules=modules.json, I assume that is correct.

Steps to reproduce

1. Visit https://www.poznatsvet.cz/?pbjs_debug=true
2. Use resource override to replace:
   https://cdn.cpex.cz/hb/prebid/prebid.min.js -> https://cdn.cpex.cz/stage/hb/prebid/8.49.0/prebid.js
3. Add debugging:

pbjs.setConfig({
  debugging: { enabled: true, bids: [{ cpm: 15 }] }
})

Expected results

Debugging mode to work with unminified version

Actual results

Error, Prebid breaks after that point

Platform details

MacOS, latest Chrome, Prebid 8.49.0

I know the path isn't there but the same thing works with the minified version, so I assume the paths is supposed to be relative, within a bundle? Not sure how this works.

On development builds, by default, it points to the dev server (as you have discovered). It doesn't work too well for what you're trying to do, and maybe we should change it - it made sense to me because I was thinking of development on Prebid itself.

this is where the path is chosen, and here's the override. You can set it explicitly with:

gulp build --dist-url-base "https://cdn.jsdelivr.net/npm/prebid.js@latest/dist/"

another option I think would work in your case would be to just include the debugging module - it won't try to fetch it if it's installed.

Thanks, building in the debugging module for the dev version turned out to be the simplest solution. Closing
