@DokiDoki1103 Thanks for catching this. The regex that APISIX accepts for this field doesn't match with the one accepted by ingress controller. I will create a fix for this. https://github.com/apache/apisix/blob/a2da5f156c433b373ba670ce9eecdfdcb4cf7268/apisix/schema_def.lua#L40C23-L40C51

@Revolyssup You're welcome, I'm using Apisix extensively. If I encounter any problems, I'll give you feedback promptly
