Unable to Access App Hosted on AWS S3 - "Invalid redirect_uri" (Error 400)

Hello everyone,

I recently deployed my application to AWS S3 and attempted to integrate it with ArcGIS Online for user authentication via OAuth 2.0. Unfortunately, I encounter the following error when trying to log in:

(view in My Videos)

ArcGIS Portal Directory Error Invalid redirect_uri Error: 400

What I Have Tried:

Registered the application in ArcGIS Online.
Added the correct Redirect URL in the app’s settings under Redirect URLs.
Verified that the redirect_uri in the OAuth request matches exactly with the registered URL.
Confirmed that the application uses the correct Client ID.

Configuration Notes:

During configuration, I replaced the contents of the config.json file as follows: Previous content:

"attributes": { "portalUrl": "https://exb.maps.arcgis.com", "isWebTier": false, "clientId": "", "title": "XBLD_AWS", "description": "XBLD_AWS", "type": "Web Experience", "thumbnail": null }

Replaced with:

"attributes": { "portalUrl": "https://exb.maps.arcgis.com", "clientId": "xy" }

I assume this change shouldn’t matter because after reverting to include the additional information, the app behaves exactly the same.

Additional Context:

The map I’m trying to display is shared only within my ArcGIS Online organization, but I suspect that’s unrelated to the issue since I cannot even log in to authenticate.

Questions:

Could my changes to config.json impact the redirect process?
Is there a specific setting in ArcGIS Online that needs to be configured for apps hosted on AWS S3?
How can I resolve or debug this issue further?

I’d greatly appreciate any help or suggestions to get the app working. Thank you in advance!

Daniel
