Adobe Express cannot fetch my

Gooday!, Adobe team & community,

I've been successfully integrating the Adobe Express SDK into my project to launch the image editor with base64 image input using the createWithAsset method. Until recently, this worked flawlessly — but now, the image no longer loads in the editor,   even though the SDK initializes properly.(thought might be a cors issue but then it worked earlier and i have my cors settings adjusted)

Here’s a summary of what I’m doing:

backend is served via Nginx at http://localhost:8000

location / {
if ($request_method = 'OPTIONS') {
add_header 'Access-Control-Allow-Origin' '*' always;
add_header 'Access-Control-Allow-Methods' 'GET, POST, PUT, DELETE, OPTIONS' always;
add_header 'Access-Control-Allow-Headers' 'Content-Type, Authorization, application-token' always;
add_header 'Access-Control-Allow-Credentials' 'true';
return 204;
}

i am using a self-signed HTTPS cert locally — the SDK loads and initializes but theres alot of errors poping in inspect while loading and could see that even when the image used to load.

I get alot of these while its loading, POST https://cc-api-data.adobe.io/ingest/?api_key=ccew-web-sdk-service net::ERR_CONNECTION_REFUSED

my createWithAssets function and the way its loading now and errors is attatched .

Has there been a recent change in the SDK that affects how a image data is sent?

Is there now a preferred method for loading assets (e.g. via hosted URLs only) or something i should do interms of CORS or where the dev server is run for adobe to fetch it properly?

Any kind of assistance or direction will be appreciated.

Thank you in advance
