Tiles blocked by CORS issue in Cloudflare

[ajh2oman]

I'm trying to implement protomaps via Cloudflare. I followed the instructions but ran into an issue with CORS. It's the same issue as https://community.cloudflare.com/t/stuck-at-cors-header-access-control-allow-origin-missing-when-using-cloudflare-workers-to-access-resources-at-r2-storage/610073.

I do have access to the .json file and tiles/0/0/0.mvt does download when requested, so I'm not sure if it is a CORS issue or if I didn't implement the files with Openlayers correctly.

You need to show us the code you are using so we can investigate what the problem might be.

Here's what I'm using for my Cloudflare Worker(attached)

what did you set the value of ALLOWED_ORIGINS to?

[ajh2oman]

'Access-Control-Allow-Origin': * for Workers and 'Allowed_Origins':* for R2

[bdon]

If your CORS header is set to '' then it is not going to work for any site. Set it to this:

They're both sent to that, I just edited the text for some reason the * was hidden on here. Is there anything else that may be blocking access?

What is a valid tileset name on https://pmaps4.ajh2oman.workers.dev and what browser are you using?

[ajh2oman]

I'm using Chrome but CORS seems to block the integration into OpenLayers

What is the name of the .pmtiles file in the R2 bucket?

https://pmaps4.ajh2oman.workers.dev/0/0/0.mvt is not a valid tileset URL.

Something like https://pmaps4.ajh2oman.workers.dev/mytiles/0/0/0.mvt is a valid URL if mytiles.pmtiles is in your bucket.
