Invalid Account ID" Error (ERROR 9426)

I am experiencing a persistent "Invalid Account ID" error (ERROR 9426) when attempting to deliver images via Cloudflare Images using a Worker on my domain, mrlipx.com. I have been troubleshooting this extensively without success, and it appears the issue lies outside of the Worker's code logic.

My Cloudflare Images Account Hash is: HUDbG83RTduFMklKurMDw

The exact error message I receive is:
ERROR 9426: The URL of imagedelivery.net has invalid account id invalid and remove the file ecschon

The full URL that my Worker constructs and attempts to fetch from imagedelivery.net is (example from logs):
https://imagedelivery.net/HUDbG83RTduFMklKurMDw/c1b39c74-1984-48ac-fcf7-a578b8ee1d00/ (Please replace c1b39c74-1984-48ac-fcf7-a578b8ee1d00 with the actual image ID you are testing, and provide the specific URL from your Worker logs if it's different).

My Cloudflare Worker's code (stripped down for clarity) is attached below. This code correctly constructs the imagedelivery.net URL based on your documentation, and includes error handling.

Despite verifying the Account Hash directly from my Cloudflare Images dashboard and confirming the URL structure ( https://imagedelivery.net/<ACCOUNT_HASH>/<IMAGE_ID>/ or /<VARIANT_NAME>), this error persists. This suggests a potential issue with my account's image delivery configuration or how my specific account hash is being processed by the imagedelivery.net endpoint.
