hi antonios855139 that is the general example, in reality when you use you need to have your actual record type as mentioned in below image; 
 recordtype!yourrecordname.fileds.image

Hi antonios855139 could you try this code by the replacing your record type in the given code 
 a!gridColumn( 
 label: "Image", 
 helpTooltip: "Test images may not represent the actual vehicle", 
 value: a!imageField( 
 images: a!documentImage( 
 document: if( 
 /*Replace with your record type*/ 
 isnull( 
 fv!row['recordType!{99b0bb09-e2c0-4f75-a70b-26f247e2d095}AA Vehicle.fields.{c7d0b689-e98f-4cb7-8477-6c63943b30a0}image'] 
 ), 
 a!EXAMPLE_DOCUMENT_IMAGE(), 
 /*Replace with your record type*/ 
 fv!row['recordType!{99b0bb09-e2c0-4f75-a70b-26f247e2d095}AA Vehicle.fields.{c7d0b689-e98f-4cb7-8477-6c63943b30a0}image'] 
 ) 
 ), 
 size: "SMALL" 
 ), 
 align: "CENTER" 
 ),

You need to have document ID in that field, the error says that, since values are null it is unable to find the image
