Thingsboard Gateway REST connector fails to initialize - thingsboard

Question

I'm trying to set up the REST connector for Thingsboard IoT Gateway and getting some errors on initialization. My rest.json config is:
{
"host": "127.0.0.1",
"port": "5000",
"SSL": false,
"mapping": [
{
"endpoint": "/sizerdata",
"HTTPMethods": [
"POST"
],
"security": {
"type": "anonymous"
},
"converter": {
"type": "json",
"deviceNameExpression": "Sizer ${name}",
"deviceTypeExpression": "default",
"attributes": [
{
"type": "string",
"key": "serialNumber",
"value": "${serialNumber}"
}
],
"timeseries": [
{
"type": "integer",
"key": "cupfill",
"value": "${cupfill}"
},
{
"type": "integer",
"key": "packsPerHour",
"value": "${packsPerHour}"
},
{
"type": "integer",
"key": "totalFruitPerMinute",
"value": "${totalFruitPerMinute}"
}
]
}
}
]
}
When I start the thingsboard-gateway service I get the following errors in the logs:
""2021-12-29 13:09:07" - |ERROR| - [rest_connector.py] - rest_connector - run - 152 - web.Application instance initialized with different loop"

I have tried this on an Ubuntu install and a Docker container and I get the same result. Any ideas on why this doesn't work?

It is an issue with aiohttp, it is already fixed in the master branch.
You can use the version from the master branch of the gateway repository or wait for the next release.
