Not able to run replication on startup?

I am looking to replicate data from one db to other db for specific channel on start of sync_gateway. I am using the following configuration for my sync_gateway

{
“interface”: “:4984”,
“profileInterface”: “80”,
“adminInterface”: “:4985”,
“MaxFileDescriptors”: 25000,
“log”: [
“CRUD”,
“CRUD+”,
“HTTP”,
“HTTP+”,
“Access”,
“Cache”,
“Shadow”,
“Shadow+”,
“Changes”,
“Changes+”
],
“replications”:[
{
“replication_id”:“continuous-filtered”,
“source”: “db”,
“target”: “http://localhost:4985/_admin/db/db-copy
“continuous”:true,
“changes_feed_limit”:1000,
“filter”:“sync_gateway/bychannel”,
“query_params”:[“channel1”]
}
],
“databases”: {
“db”: {
“server”: “walrus:”,
“bucket”: “db”,
“users”: {
“GUEST”: {“disabled”: false, “admin_channels”: [""]}
}
},
“db-copy”: {
“server”: “walrus:”,
“bucket”: “db-copy”,
“users”: {
“GUEST”: {“disabled”: false, “admin_channels”: ["
"]}
}
}
}
}

Error logs for syn gateway

Try changing target to: http://localhost:4985/db-copy

The SG Replication docs have more details: https://developer.couchbase.com/documentation/mobile/1.5/guides/sync-gateway/running-replications/index.html

thanks @traun changing target works for me
