'http exception when calling webhook' on localhost

^{Originally posted by **kdichev** September 18, 2022}
Hi, I am developing locally with hasura running with docker-composed container on port 8080, I have a functions api on port 8000. I've setup my action with env variable as so `{{ACTION_BASE_URL}}/subscriptions-config` and the value of the variable is `http://host.docker.internal:8000/api`. When I call the action I get `'http exception when calling webhook'`, but I am using the same approach for hasura events that calls the same functions api which work as expected. Shouldn't this just work for actions as well? Seems like a bug. I am on a mac machine. I've seen a few similar issues here but seems like it's hacks rather than real solutions (I would expect actions to work as events work with this workflow)
