File upload field not working in AEM 6.4.1

[#1]

AEM version 6.4.1.0

File upload field not working. We need ability to upload file from local system and not DAM.

Tried below steps :

1] http://localhost:4502/mnt/overlay/wcm/core/content/sites/properties.html?item=/content/we-retail/it[.... We-Retail has a tab "Thumbnail", Tried on similar lines but getting error :

07.03.2019 11:30:25.933 *ERROR* [0:0:0:0:0:0:0:1 [1551938425928] POST /content/requests/re3/_jcr_content HTTP/1.1] org.apache.sling.servlets.post.impl.operations.ModifyOperation Exception during response processing.

org.apache.sling.api.resource.PersistenceException: Property is protected: jcr:createdBy = admin

and a long stack trace.

2] Tried using fileupload provided in v2 core image component. Not working.

But none of them are working.

Any thoughts/pointers on this will be really helpful.

Please ignore the above question. jcr:created property was being explicitly set on page jcr via code  which was causing issues.

Hi All,

Further requirement on this would be to : create a link to the uploaded file[uploaded from local system, not DAM] in the the page properties dialog, so that on clicking the file uploaded is downloadable.

Any thoughts on how to go about this will be really helpful.

Can you please post a screenshot of exactly what you want to do. Seems like you want a link on page properties dialog that downloads a file.

How did you resolve the 500 error? I'm getting the same issue while uploading image from page properties.
