Loadbalancer Pool Creation

I am trying to create an origin pool in cloudflare but I constantly get this error.

only ASCII letters, digits and ‘_-.’ are allowed in name: validation failed (Code: 1002)

{“minimum_origins”:1,“check_regions”:[“OC”],“notification_email”:“[email protected]”,“notification_filter”:{“pool”:{“healthy”:null}},“origins”:[{“name”:“server-1”,“weight”:1,“enabled”:true,“address”:""}],“name”:“us-west1”,“description”:“US West Region”}

This are the headers of the data I am sending I cannot see any issues in the name characters.

I am having the same error is anyone looking at this ? 4 years ago ?
