hi,
today I installed Flow Linter and have been reported many errors ...
I fixed most of them but I have 3 errors pending ...
1° error
```auto
[msg] Parsing error: Unexpected token
```
I have this error in all the function where I use
setTimeout(() =\> { node.send([output[0]]) }, 2000);
like this:
```auto
const output = [null];
output[0] = { reset: true };
setTimeout(() => { node.send([output[0]]) }, 2000);
```
2° error
```auto
[msg] Do not access Object.prototype method 'hasOwnProperty' from target object.
```
this is the function:
```auto
if (msg.hasOwnProperty('ui_control') && msg.ui_control.callback === "renderComplete") {
var msgOut = {
payload: {
command: "selectRow",
arguments: [1],
returnPromise: false
}
}
return msgOut;
}
```
3\* error
```auto
[msg] 'suncalc' is not defined
```
and this is the function:
```auto
function sunData() {
return suncalc.getSunTimes(new Date(), 43.690419, 10.816769);
}
function moonData() {
return suncalc.getMoonData(new Date(), 43.690419, 10.816769);
}
```
Can you help me to fix these errors?

Hi @Giamma
I think you've hit some areas the flow linter doesn't handle well today and is in need of some updates.
Issue 1 - I think this is because you're using `=>` functions which is newer syntax than the version of eslint bundled in the flow linter supports.
Issue 2 - This is actually a genuine warning. Rather than use `msg.hasOwnProperty('ui_control')`, the better syntax is `Object.hasOwn(msg, 'ui_control')`
Issue 3 - The linter doesn't know about the additional modules being imported into the function node (ie `suncalc`). The linter needs updating to handle that properly.
So, other than issue 2 which you can address yourself, the others are issues with the linter itself.

In setting.js I commented this line:
```auto
module.exports {
nrlint: require("./.nrlintrc.js"),
}
```
and re-start node red but I always have the linter sidebar available in my editor,
how can I delete it?

And removed the dependency?
```bash
cd .node-red
npm remove nrlint
```
Can be done in Palette Manager too.
