[CERT-TEST-FAILURE] TC-TSTATM-3.2: "No Schema found for Attribute" errors during post-reboot subscription resumption.

Test Case

TC-TSTATM-3.2

Reproduction steps

While validating TC-TSTATM-3.2 on the latest master TOT, the test case passes successfully. However, error messages are observed during execution while handling the post-reboot subscription resumption.

During subscription resumption after the DUT reboot, the Python controller receives ReportData for the manufacturer-specific cluster 0xFFF1FC21 on endpoint 1.

TypedAttributePath.post_init does not have a generated schema entry for this cluster, resulting in a KeyError inside Attribute._handleReportEnd.

Error KeyError: 'No Schema found for Attribute 1/4294048801/0'

Similar errors are observed for the manufacturer-specific/global attributes reported under the same cluster.

Observed Behavior

1. TC-TSTATM-3.2 passes successfully.
2. Error messages are observed in the middle of the test execution.
3. The errors occur during post-reboot subscription resumption when processing ReportData.
4. The Python controller continues execution after the errors and the test completes successfully.

Expected Behavior

The test case should execute without unexpected KeyError messages during subscription resumption.
