I am using QGIS 3.16, and I am trying to run the “Service area from layer” function on approximately 400 layers (200,000 starting points in total), I am also due to be repeating this at a range of distances so looking to use Python. Also, I cannot merge together as there are 1,000s km of road and just not feasible to set it running for next month.

I have been trying to run the “Service area from layer” function via Python and I can get it to accept my road and node layer, which have to have the same name (but are in different folders), and then output this to a different folder. The issue is that the table contains a row for each service area, but there is no geometry written. Below is the code that I have been working on but reading about I can see that there is something relating to FeatureSinks but not sure how I go about including this.
