"INT is not a region builder" error in JOIN function

[MicheleRoar]

with this query:

chip_promoter_0 = promoter.join(experiment=histone_marks,
                         genometric_predicate=[gl.DL(0)],
                         output='INT')

I got the following error. The same query works if the output parameter is LEFT, RIGHT or CONTIG

Can you try using INTERSECTION instead of INT?
