hi @Logan.KeexFrame
you have to probably have to follow this
Material Expression Dynamic Parameter
Type control +F and Dynamic which will move the document to the required area

Disallowed is the way Fortnite protects against UE code not supported in UEFN

Ive got the same error. Had to go through all my niagara system and remove all dynamic parameters and put all the values possible into the main material blueprints. This fixed the error however my niagaras looking terrible so im guessing this is a uefn problem.
