Cause?:
In

Meross/lib/api.js

Line 62 in 7a9ea92

let url = new URL(request.url);

, logRequest() fails if argument request does not contains url .

My workaround:
In

Meross/lib/api.js

Line 98 in 7a9ea92

} else if (error.request) {

,Fix
} else if (error.request) {
to
} else if (error.request && error.request.url) {

Log with applying workaround:
Shows error normally (without TypeError).

Error connect EHOSTUNREACH 10.10.10.155:80

Well the true error is actually that the device you specified at 10.10.10.155 doesn't have the Meross HTTP API or doesn't exist. It's unusual for a Meross device to use anything but 10.10.10.1 except when it's connected to your WiFi.

I mean 10.10.10.155 is just one of the example to manually cause network-related error, so this address does not have meaning.

What I wanted to say is, when network-related error happens, some of that that does not contains url in error.request, the TypeError cause, and we cannot get what the real error is.

Sorry, there are no need to add sudo, so I fixed logs.
