Universal Editor status 302 to localhost:8443

[JaymeSantos]

Hi all,

I'm facing an issue with Universal Editor connecting to my local AEM Author. I'm following react headless tutorial with wknd boilerplate and running local-ssl-proxy --source 8443 --target 4502 / local-ssl-proxy --source 8001 --target 8000 /  node universal-editor-service.cjs as recommended. Even so, after added the data-aue-prop, data-aue-type, and data-aue-label (instrument-to-edit-content) the editor tries to fetch CF details from 8443 when selecting the "team members" component and get status 302 with no body to the following endpoints:

• https://localhost:8443/content/dam/my-project/en/john-doe.4.json
• https://localhost:8443/content/dam/my-project/en/alison-smith.4.json

Still able to add, remove and edit the members and every property of the teams component. But for selecting a CF from the modal I have no options to DAM folders and the same 302 issue in the network console to the following endpoint:

• https://localhost:8443/bin/querybuilder.json?orderby=%40jcr%3Apath&orderby.sort=asc&p.limit=-1&p.hit...

When acessing any of those endpoints directly from the browser I get correct JSON in response.

Also, I have successfully fetch 8443 data from the frontend openned in UE. Seems the local instance is redirecting UE to the void. Is it a missing configuration? Any clue to solution?

Hi @JaymeSantos 

1. Allow Anonymous Access to QueryBuilder
Go to: http://localhost:4502/system/console/configMgr/org.apache.sling.engine.impl.auth.SlingAuth
enticator
In Authentication Requirements, add:
- /bin/querybuilder.json
- /content/dam/my-project
2. Login on 8443
Visit https://localhost:8443 in browser
Login to AEM Author before launching UE
3. Use Better Proxy
Replace:
local-ssl-proxy --source 8443 --target 4502
With:
npx universal-editor-proxy --port 8443 --aem-author-port 4502
Try this and the CFs should appear in the picker.

Hope this helpful.:)

Regards,

Karishma.

already authenticated from 8443

i have also tried to follow instructions from https://experienceleague.adobe.com/en/docs/experience-manager-65/content/implementing/developing/hea...

but some of the services was not found as expected in configMgr, missing: `Adobe Granite Query Parameter Authentication Handler` and `Universal Editor URL Service`

i have noted the following

but unable to access `feature pack` url https://experience.adobe.com/#/downloads/content/software-distribution/en/aem.html?package=%2Fconten...

i have the most recent aem sdk running, should `cq-6.5.21-universal-editor-1.0.0.zip` be installed in my instance? download it from where?
