[ferdaarikan]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

Similar to #1254 and also mentioned here graphql-dotnet/server#1110

When pre-request or post-request scripts are enabled worker fails to initialise and scripts do not run.

Expected Behavior

Pre/Post request script to execute without errors

Steps To Reproduce

The fiddle provided in issue #1254 https://jsfiddle.net/imolorhe/zrjh2x08/27/ also reproduces the same issue. Try a simple schema query when post or pre request script is enabled and populated.

I'm attempting to fix this issue. In the meantime you can disable the beta version of the scripts and fallback to the old behavior to unblock yourself (although I would recommend enabling the beta version again when you're done since eventually that would be the only option, and it would be good to know that it still works as expected for you).

The last fix didn't work because angular has disabled processing import.meta.url pattern for fetching assets at runtime, so will need to figure out another way to get the compiled JS file path for the web worker.

Ooh.. actually this might work.

[imolorhe]

Okay this issue requires a different solution. We may have to move away from using web workers as they are very strict with enforcing the same origin policy of the browser. The above solutions don't work because the web worker scripts are complex enough that loading them via blobs don't work.

[imolorhe]

This should be fixed now in v7.0.1. Can you verify?

Actually it still wouldn't work just yet, since we expect a trusted origin. I'll remove that check in the next release.

This is fixed in v7.1.0! 🎉

@imolorhe thanks for the fix and demo. I tried and this works in my own environment as well.
