Filtering Out Old Intune Data from Service Graph Connector

[J-J-J]

So our particular Intune instance keeps systems that haven't checked in for 9 months before they are purged. This isn't normally an issue, except many of the computers are re-imaged during their lifetime. After they are re-imaged, there are two objects in Intune that now point to a single CI. Due to the long lifetime of the old objects in Intune, we now have items being updated by two Intune objects for 9 months.

I'm trying to have ServiceNow skip/ignore computers in Intune that haven't checked in within the last 2 weeks. We already have the data from them in the CMDB and I don't feel the data from them is particularly useful. I think I can filter these through the IntegrationHub ETL. I've found that I can add before scripts on the SG-Intune Computers data source and these scripts could potentially instruct ServiceNow to skip rows during the import. I've tried access the "lastSyncDateTime" from these scripts and I don't seem to be able to. I've tried referencing them from:

input[0].payload.items[1].values.lastSyncDateTime and input[0].payload.items[1].values.u_lastsyncdatetime and neither seem to exist. I've also tried iterating through the keys to the object under input[0].payload.items[1].values and I don't seem to be able to (Though I know the "name" attribute exists).

Am I heading down the right path for filtering these rows out? If not, would you please point me the correct way?

If I am heading down the right path, any ideas why I can't see the "lastSyncDateTime" or iterate through the attributes on the payload object? Any help here is much appreciated.

Thank you!
