Designing Appian Records Part 1 Configure the records list

I am on the Exercise where I have to change the image to a document image I was initially getting an error as it was like the documents was missing there but managed to add the images to my app.

I have keyed the code under the expression editor.

a!imageField(
images: a!documentImage(
document: fv!row['recordType!{c20ff609-5f40-4fea-8800-074abc464c7c}AX Vehicle.fields.{f1cb1cdc-1134-40e8-b30b-0b90d32da455}vehicleimage'],
caption: fv!row['recordType!{c20ff609-5f40-4fea-8800-074abc464c7c}AX Vehicle.fields.{f1cb1cdc-1134-40e8-b30b-0b90d32da455}vehicleimage']
),
size: "SMALL"
)

I now get this error below.
