@ravimeda , the 202 return pattern is for our old set of resources that we have not yet moved to the 201 pattern. However our new resources are now using the 201 pattern (that are being changed here in this changeset) #Resolved

[jamesvoongms]

@ravimeda I have changed the new version 2025-10-01-preview to now use v6 as requested #Resolved

[ravimeda]

Keep the 202 for existing resources. Only for the new RTs avoid 202 for PUT.
