Custom application pattern fails with error

[thomasbueck]

Hi,

I have created a custom application pattern, which runs fin in debug mode.

I have registered the pattern (sa_pattern_prepost_script) under "Lightweight process Info".

I created the process classification and linked the pattern/classifier to the probe/pattern.

I also created a deletion strategy under sa_ci_to_pattern.

The discovery log is fine and completely green apart from the last step - there I get this error

Run Delete Strategy

2026-06-01 07:02:03: Using Snapshot based deletion model...

Delete Handler

2026-06-01 07:02:03: Failed to find CI matching u_cmdb_ci_workato from new snapshot payload

Any ideas on what I have missed?

Hi @thomasbueck 

1. Check IRE Rule

• Navigate to Configuration > Identification/Reconciliation > Identifiers.
• Open the identifier rule tied to your u_cmdb_ci_workato table. Make sure the rule has active "Identifier Entries" (like name and version) and that the discovery payload actually collects these exact matching attributes

2)Validate containment rule

1. Navigate to the CI Class Manager-> search for cmdb_ci_appl / custom Workato CI class.
2. Ensure there are explicit Containment Rules configured. If the parent relationship is missing in the payload, the dependent child CI will fail to process

3) Review the Identification Logs to see exactly which attributes the payload is sending and why the IRE is rejecting or unable to identify the device
