[BUG] Error when executing 'tuya-lan-find'

[codydalerodgers]

What is the bug?

_I am trying to follow the instructions as documented but on the step where I am supposed to run tuya-lan-find I am getting the following error:

/usr/local/lib/node_modules/homebridge-tuya/bin/cli-find.js:29
const proxy = Proxy();
^
TypeError: Proxy is not a function
at Object. (/usr/local/lib/node_modules/homebridge-tuya/bin/cli-find.js:29:15)

at Function.executeUserEntryPoint [as runMain] (node:internal/modules/run_main:81:12)
at node:internal/main/run_main_module:23:47

How can one reproduce the bug?

Following the install of homebridge-tuya-lan, try to execute 'tuya-lan-find'.

What is the expected behavior?

It should show a QR code.

What is your host/environment?

Homebridge v1.8.2

Do you have any screenshots?

Do you have any additional context?

N/A

I troubleshot and patched the config it can be edited in the homebridge terminal - there is still an issue with the certificates included though

same issue here

I used @jdmu patch but get a bad CA cert error

[maciej-nawrocki]

Same here:
Failed to intercept secure communications. This could happen due to bad CA certificate.Error: connect ECONNREFUSED 0.0.0.0:46741 PROXY_TO_PROXY_SOCKET_ERROR

Using homebridge docker image I am having the same issues. The connection refused was after iPhone setup.

MITM proxy seems to have updated and wasn't pinned correctly.

SOLUTION: This project is deprecated, use https://github.com/iRayanKhan/homebridge-tuya instead.
