Survey123 xlsform pulldata(@layer not working

SteveBrewer — Fri, 22 Mar 2024 23:22:35 GMT

I am trying to get this work after trying to work with json. Where based on a geopoint question it returns a value.

pulldata("@layer", "getValueAt", "attributes.Label", "https://agency_name.maps.arcgis.com/home/item.html?id=5fa01c8e666740968c727b8a81f78ef7&view=service", ${Segment_ID_Point})

Hi Steve, my guess would be that

- first : you have in fact to use the REST URL of your layer (don't forget the '/0' at the end), like

- second, you have to add a buffer instruction at the end of your URL if you want to capture the label near the point position your users will enter. ("?distance=XXX&units=YOURUNITS"

The help topic might be of help : Formules—ArcGIS Survey123 | Documentation

Have a nice day

Thank you Chris we still had some issues with this and after talking with support we decided to go with a geoshape question and ran into this issue.

TypeError: Cannot read property 'toString' of undefined in expression: pulldata("@layer", "getValueAt", "attributes.Label", "https://services2.arcgis.com/Uq9r85Potqm3MfRV/arcgis/rest/services/SCAT_Segments_Polygon/FeatureServer/0", /Scat_Application_v3_0

if you have any advice that would be great thank you for your help!

Hello Steve, sorry for the delay. I hope you solved this problem since.

It looks like there is a problem in one argument of your formula. If you don't already solved the problem, I suggest you post more informations, perhaps a sample of your .xlsform. It seems that the line you copied is not whole.

Sorry for the reply a year later Steve...

I am working on a similar project that required this pulldata function and found that wrapping a string() function around it solved the problem.

Previous statement:

pulldata("@layer", "getValueAt", "attributes.X", ${arcgis_rest_url}, ${location})

Solved:

string(pulldata("@layer", "getValueAt", "attributes.X", ${arcgis_rest_url}, ${location}))
