Hi @NilSkillWill
Please go to the exact location of the list you say has this name
Is it a Person Column DataType? Or you have named it Full name?
Go to the List
Click List Details
In the List of Fields Click on the Full name one you say exists
Please then look in the URL at the end will be the actual name of the field.
See if it matches, if it does, then you are pointing at the wrong environment, or site.
If I have helped you, I would really appreciate if you please Mark my answer as Resolved/Answered, and give it a thumbs up, so it can help others
Cheers
Thank You
