I hit the same issue. I suspect it occurs when using Application Gateway v1

I have faced same issue, while attempted to create AGW Standard tier (v1) and the configuration of this version AGW does not supports the argument "priority". That is mandatory for all AGW tiers, but shoud be mandatory only for tier Standard_v2 and WAF_v2. It's a blocker issue
