Using SummarizeWithin In Geoprocessing Service

Hey Geoprocessors!

Something interesting I just ran into that I thought I would share. I don't know how many tools this extends to, or how many of you may already know this, or who of you might know other ways around it, but I'm sharing nonetheless.

I have a simple GP tool, published as a web tool to Enterprise 10.9.1 that takes a user-defined point, generates a buffer, and uses SummarizeWithin() to calculate field stats from a hosted feature layer. The first version I built used a hard-coded value table for the sum_fields parameter, i.e.

[['abovepoverty','mean']]

This worked fine when consuming in a web app. The second version of the tool actually took the multi-value choices from another tool parameter, split them, built the value table, and assigned it to a variable, which was then used as the argument to sum_fields, i.e.

stats_to_calc = [[field, 'sum'] for field in summary_fields.split(';')] SummarizeWithin( ..., sum_fields=stats_to_calc )

After publishing this second version, the tool always failed, with

ERROR 100014: Summarize Within failed. Failed to execute (SummarizeWithin).

According to an Esri support doc, this has to do with one of:

Feature Class name length
Filepath length
Field names incorrect/too long

None of these made sense to me. Finally, I decided to try one more code alteration, so now the calculation of the value table for the sum_field parameter happened inside the SummarizeWithin() function call, i.e.

SummarizeWithin( ..., sum_fields=[[field, 'sum'] for field in summary_fields.split(';')] )

When I published the tool with this alteration, the tool successfully generates my output buffer and summary table. I am not sure why it only likes this methodology, but that's what I've found.

Anyone insight is of course appreciated 🙂

That's very interesting. Seems like a serialisation quirk.
