Fatal Error when trying to update a rule

[KooBikes-Ryan]

I am trying to update a rule and every time i get the following error. Fatal error: Uncaught Client Error (400): The field 'image_file' is invalid. I have included the image_file with the previous value and also tried with NULL and it still comes back with this error and does not update the value that i need to update.

Do you still need help with this? Paste the code being used to update the rule image.
