But in the same couchbase server i have created travel-sample from sample buckets .
so when i change the bucket to travel-sample with the same user it has same access on all buckets then my sync gateway starts and works normally .
what could be the issue ?
i also need steps to open admin console on 4985. ( as this is a test environment i m not bothered about security .
Appreciate your responce.
for reference my config file:
{
“log”: [""],
“databases”: {
“db”: {
“server”: “ec2-.us-east-2.compute.amazonaws.com:8091”,
“bucket”: “Bucket1”,
“username”: “test”,
“password”: “password”,
“enable_shared_bucket_access”: true,
“import_docs”: “continuous”,
“users”: { “GUEST”: { “disabled”: false, “admin_channels”: [""] } },
“sync”: function (doc, oldDoc) { if (doc.sdk) { channel(doc.sdk); } }
}
}
}
