Error: Could not load service "@dashevo/insight-ui"

[allgama]

I followed this installation guide https://docs.dash.org/en/stable/developers/insight.html
but I can't get the service to start:

dashcore-node start
/usr/local/lib/node_modules/@dashevo/dashcore-node/lib/scaffold/start.js:124
throw new Error(
^

Error: Could not load service "@dashevo/insight-ui" as it does not support necessary methods and properties.

Here's my dashcore-node.json config paths are ok, I double checked this.

{
"network": "livenet",
"port": 3001,
"services": [
"@dashevo/insight-api",
"@dashevo/insight-ui",
"dashd",
"web"
],
"servicesConfig": {
"dashd": {
"spawn": {
"datadir": "../.dashcore",
"exec": "../dashcore-0.13.2/bin/dashd"
}
}
}
