Check the file, you’ve probably missed a comma or added a comma. Commas separate a list, take it like this
One, Two, Three, Four but in the files it’s made to look neater by being like this
One,
Two,
Three,
Four
Four is the last part of the list, so there is no comma, Three is part of the list, so there is a comma.
