Unhandled Rejection in decoder worker

[sammaxwellxyz]

The pool'd decoder worker doesn't handled rejections

https://github.com/geotiffjs/geotiff.js/blob/master/src/worker/decoder.js

https://github.com/geotiffjs/geotiff.js/blob/master/src/pool.js#L74-L87

This is highlighted when trying to use a WEBP encoded GeoTIFF via Open Layers with Safari. I assume something due to the way the data is passed from openlayers and perhaps the lack of this API https://caniuse.com/mdn-api_htmlcanvaselement_toblob_type_parameter_webp.

or just safari access control checks

At this point I'm not sure how/why but it seems to work when I render with geotiff.js directly but not via openlayers.

console shows this error:

Not allowed to load local resource: blob:null/ced499f8-0af1-475b-bec8-72769f72de4e

Cannot load blob:null/ced499f8-0af1-475b-bec8-72769f72de4e due to access control checks.

Unhandled Promise Rejection: InvalidStateError: An error occurred reading the Blob argument to createImageBitmap

I intend to come back with more information, but the root cause seemed like a worthwhile fix itself

Hey @sammaxwellxyz

Thanks for reporting this! It is true that we are not properly propagating errors originating in workers. I'm working on a solution.
