ID:265023 Can't save or compile Signal Tap File -- operator <name> has only numerical operands but must have at least one non-numeric operand

CAUSE: The specified operator has only numerical operands, but the operator must have at least one non-numeric operand. As a result, the Quartus Prime software cannot save or compile the Signal Tap File (.stp).

ACTION: If you manually edited the STP File, restore the STP File to its original state or create a new STP File. If you used an EDA tool to generate the STP File, contact the EDA tool vendor for technical support regarding this message.
