Use esri/rest in webworker error

QingXu — Tue, 19 Oct 2021 16:42:03 GMT

I am trying to use javascript api esri/rest/query in a webworker.

But at run time, it got error 'typeError: _global_js__WEBPACK_IMPORTED_MODULE_1__.default.invokeStaticMessage is not a function".

Does Arcgis javascript api support using esri/rest/query in webworker? If yes, could you help to let me know what I am missing?

Below are parts of the code in webworker?

import * as query from '@arcgis/core/rest/query';

...

query.executeForCount(queryOptions, { url: layerUrl }); // This causes the error above.

Thanks!

I tested out doing a query in the worker using this sample without errors.

https://github.com/Esri/jsapi-resources/tree/master/esm-samples/jsapi-custom-workers

Look over that sample and see if you can find some tips on how to get it to work in your project.

I didn't use the worker framework from the javascript api. I just implemented a regular webworker in angular. Do I need to do any esri config setting to make the webworker working?

Thanks!
