Sorry - missed something here. Because you're directly using the
output from the child algorithm as your algorithm's final output, you
should also pass the

Hi,
I had the same issue. I had to loop over the output vector layer (child alg) to
feed the sink (main alg). Maybe is not the simpliest/shortest/fastest, but it
works.
Something like that :
o = processing.run

You're making this tricky for yourself! Cut out everything in
processAlgorithm related to self.INPUT, and just pass the parameter
value direct to the child algorithm to
Hi all,
I am getting my feet wet with the new QGIS 3 Processing script syntax. In my
script I want to use some other processing scripts from the toolbox. I think
I got most things right, but I do not get a result back. For testing I just
try to use qgis:pointsalonglines on a temporary
