The master and wod branches of LPS and ABA are out of sync.

Both wod and master branches of ABA use DescribeLPSSource which in term needs a category as returned by LPS' FilterIterator function. A change introduced with 947804d added the category return to that function but only on the master branch. This leads to error messages on the wod branches because DescribeLPSSource does not return a string and thus format and string concatenation fail (here and here)
