Getting below error in a simple Add vehicle form that I created during training. File upload control is not working at all

 This is how the File upload control has been configured

a!fileUploadField(
label: "Image",
labelPosition: "ABOVE",
target: cons!AX_DOCUMENTS_FOLDER_POINTER,
maxSelections: 1,
value: ri!vehicle['recordType!{2f4a1797-5b65-4891-a7cf-42ddbb49c8a6}AX Vehicle.fields.{ac064698-12ee-46cc-aebd-629ecc0dedae}vehiclemileage'],

Can't find any forEach loop in the code and the code looks fine as well. Can you check the type of vehicle rule input and if you are passing any value to it then please share the code.

Hi, 

File upload control is not working at all

You have passed the wrong variable in value.

Umm will it be an issue? I mean it's just in the display value, file is not getting displayed but it is still getting saved.

As I have mentioned in the quotes author is saying file upload is not working.
