Unable to publish private app
Hello everyone,
We are working on an app built with App Builder.
I would like to try the publish process. I saw this documentation : https://developer.adobe.com/app-builder/docs/getting_started/publish_app/ .
The problem is, when I am on the "App Builder applications approval process" page, I am unable to upload an icon. I always get this error :

I tried with very simple images like :

And more complex... Without any success.
I also checked the error from adobe server... It seems to be a server error :
{
"errors": [
{
"message": "500: Internal Server Error",
"locations": [
{
"line": 2,
"column": 3
}
],
"path": [
"uploadXRIcon"
],
"extensions": {
"code": "INTERNAL_SERVER_ERROR",
"response": {
"status": 500,
"statusText": "Internal Server Error",
"body": {
"id": "5c8a8b48-9783-4060-a361-0b0ca4afc4f0",
"messages": [
{
"template": "ERR_MSG_RETRY_ON_INTERNAL_ERROR"
}
]
}
}
}
}
],
"data": {
"uploadXRIcon": null
}
}
Could someone help me ?
Thank you in advance.
Damien.
