Getting [object Object] in quick edit of list

Hi,

I'm Having a picture column(getting the image from document library with url) and lookup column(i.e document type) i'm using json formatting

when i view it in normal it is showing the link 

and when i do quick edit it is showing as object object

so is there any custom json format where i can the name of image instead of object object kind

and i have used following things but of no use:

"txtContent": [$FieldName.columnName]
"txtContent": "[$FieldName.displayValue]"
"txtContent": [$FileLeafRef]
