Hi there! Did anyone try to initialise Ray service from Prefect Service on k8s? Im currently getting an error of missmatched keys:

I can initialize it internally in the Ray service, but there is a problem in connection between the srvices
Hey @Aleksandr Glushko, noone on the team has Ray experience, but we’ll see if the community can chime in.

Does this look like your issue?
Thank you for the reply, @Kevin Kho! Sorry, that i have posted it here, i was thinking mb i have a wrong way of Ray initialisation . I have seen this post, googling around, unfortunately it didn’t provide me any idea about working out the issue
Oh no worries at all. Yeah this issue looks hard
