I suggest having Output:VariableDictionary in the IDF format so you can copy from the .RDD to your IDF file without error:

Output:VariableDictionary,
   IDF,                                    !- Key Field
   Unsorted;                               !- Sort Option

cf https://bigladdersoftware.com/epx/docs/22-1/input-output-reference/input-for-output.html#inputs

what you're looking for is either general:

Output:Variable,*,Baseboard Electric Energy,hourly;

or keyed:

Output:Variable,Zone A BASEBOARD,Baseboard Electric Energy,hourly;
