Failed to Export HFL with attachments to FGDB of Survey123

[Hussam_AlJabri]

Hi there,

I have a hosted feature layer of a Survey that published by survey123connect‌ and it has attachments around 10K. I couldn't export it as FGDB by using different ways as listed bellow:

* Using Portal For ArcGIS:

Returned an Error:

* Using Create Replica:

Error handling service request :Could not find service. Service may be stopped or it may not be configured.

Log files:

PortalAdmin:

Failed to export item 'S123_xxxxxxxxxx_FGDB.zip' (id:xxxxxxxxxx). ERROR 999999: Error executing function. Failed to execute (Export Service). Failed.. Job ID: 'xxxxxxxxxx'

ArcGIs Server:

Also, Once this HFL didn't restore once I restored the Full Backup of Enterprise.

I am wondering if it is  corrupted and how to solve this issue! @arcgis enterprise
