Recently , I have come across this issue with Power Automate while I am trying to create a record using “Create a new record ” action with Common Data Service(Current environment) connector based on some trigger.

I am not doing any complex stuff, just creating a quote line record and referencing a quote record. Referencing records is as simple as using dynamic content and populating it to a lookup attribute right !!! No, its not. Let’s see.

I just run the flow with the above setup and flow run got failed with “Resource not found for the segment ‘c262238e-fc89-ea12-ba11-000d3ab615df‘”

After some digging , found the cause. The new CDS ( Current environment) is the culprit. Issue is with the way of referencing attributes .It expects referenced attribute values in “Odata Id” format i.e

EntityNameInPlural(Record’sId/GUID).

So here in my case, for quote lookup attribute I should give like /quotes/(Record’s Id/GUID).

After making the above change, flow has run successfully.
