Hi
We are starting to have problems with our Cloudflare worker which we are using to resize images.
It depends on which Cloudflare data center the clients connects to (CF-ray).
let imageURL = "https://xxx.blob.core.windows.net/images/test.jpg";
let options = { cf: {
image: {}
}}
options.cf.image.height = 500
options.cf.image.width = 500
return fetch(imageURL, options)
The above code will fail on the following data centers
The response will return a:
On most Cloudflare data center the code still works
The last change we did on the Cloudflare JavaScript worker was over 2 months ago.
So apparently it depends on which Cloudflare data center the Cloudflare is running on.
Am I the only who has discovered this?

Hi, we have same issue. People from Scandinavia see same error but not me from CE. Maybe we can force worker to use specific datacenter.

I have recorded a video showcasing the error
In the video I have created a super simple new worker
index.js
addEventListener("fetch", event => {
event.respondWith(handleRequest(event.request))
})
const getLastItem = thePath => thePath.substring(thePath.lastIndexOf('/') + 1)
async function handleRequest(request) {
let url = new URL(request.url)
let imageURL = "https://cloudflaretesting.blob.core.windows.net/assets/TESTCHPA0000.jpg";show original

Please let me know if you figure that out. (I haven’t found the option yet)

Based on Azure support looks like some datacenters where workers are executing call http instead of https. No more info yet.

Yes it seems to relate to Azure Blob Storage.
I have created a AWS S3 storage and uploaded a image
And created a new worker using the AWS S3 and that is working fine, no matter which Cloudflare data center is used
NB I tried to switch from Azure Blob in West Europe to US and that did not change anything
We resolved the issue by disabling the Require secure transfer in the Azure storage configuration.

Same here.
I faced same problem. I use Azure Storage Blob and Cloudflare Image Resizing through Workers.
The worker was able to get binary from Azure Storage Blob without cf resize otions.
Then, I found this thread and I tried this and It has got work.
We resolved the issue by disabling the Require secure transfer in the Azure storage configuration.
I hope Cloudflare team report the reason to use http between Azure Storage Blob and their Image Resizing.

Hi Team,
Can you tell me if you still face the trouble.
If the problem still persists, more tickets will be helpful.
Thank you.

It seems to have been resolved.
This is how I tested:
Enabled the Require secure transfer in the Azure storage configuration.
Used VPN to test different data centers
FRA & LUX did not work before. They are working now.
Data centers checked today
