Unable to upload images via paperclip on rails 5

error

Error while uploading the image

I'm unable to upload an image in my nested scaffold form.

All other fields are getting in the database except the image. Please help!

I am on rails 5.2 and using paperclip for image uploading and images need to be uploaded on AWS.

I am not getting any errors its just the images are not entering the database.

Thanks!
