Meraki Robust Transformer having issues and not loading data into CI table

mullala — Fri, 28 Feb 2025 18:43:54 GMT

I am running the Meraki Data Source - SG-MerakiDevices, and once the data gets loaded into the Data Source table, the Robust Transformer is failing and throwing the following error which I attached

Do we need to change anything in the Robust Transformer to get it to work? If so, what modifications are required?
Below are the references images for Datasource and Robust Transformer

I have no idea what this is about, but the issue is with an unexpected null.

Can you transform that into a 0 or something, or test for a null and act on that?

Is this about the ServiceNow graph connector?

I am trying to find which column is generating null, but not able to find it in logs..

The bug fix for Meraki ServiceNow Graph Connector has been released as v1.5.1. This update addresses specific issues encountered in version 1.5.0, including the "Invalid Entity class" and "Missing entity mappings" errors. To resolve these issues, we recommend that customers take the following actions:

Upgrade the Meraki ServiceNow Graph Connector to version 1.5.1.
Follow the instructions in the Setup Guide within the ServiceNow instance, specifically the step titled "Execute Fix Script." Please see the image below for details

Making any changes to the entity mappings or robust transform will cause errors even after upgrading this connector. If any changes are made to these mappings, please uninstall and reinstall the connector. Ensure that you follow all the steps in the guided setup accurately after installing again.

@shwpalan After @obrigg recommended us to use 1.5.1 we tried the config from scratch by running fix script we now able to see the networks, organisations data and also robust transformer working fine..

Thank you!
