	// Description: This EnvoyFilter does not have a priority and has a relative patch operation (NSTERT_BEFORE/AFTER, REPLACE, MERGE, DELETE) and proxyVersion set which can cause the EnvoyFilter not to be applied during an upgrade. Using the INSERT_FIRST or ADD option or setting the priority may help in ensuring the EnvoyFilter is applied correctly.
