[Bug] Gnirehtet failed to run, Unexpected 'somp_thr', was expecting 'package:'

[Unknown78]

Backgrounds

OS: Windows 11
Release package: Escrcpy-1.27.6-win-x64.zip

It was fine with the previous release of Escrcpy-1.27.5-win-x64.zip

---

Steps to reproduce

1. Connect the phone with USB
2. Run Escrcpy.exe
3. Click Gnirehtet

An error in yellow font color with exclamation mark shows up:

Unexpected 'somp_thr', was expecting 'package:'

I did try to reset the preferences, but it doesn't work.
I did try to enable the Gnirehtet Fix option, but it doesn't work.

An interesting thing is that, after I click the button, the debug log shows one line of error:

[2024-12-07 17:52:29.640] [error] relay.gnirehtet.process.stderr.data: 2024-12-07 17:52:29.638 ERROR Main: Execution error: IO error: Only one usage of each socket address (protocol/network address/port) is normally permitted. (os error 10048)

@viarotel still not fixed with Escrcpy-1.28.3-win-x64.zip

[viarotel]

I analyzed your error because the port 31416 required by Gnirehtet is occupied, and I tested my phone in v1.28.3 and it works fine.

That doesn't make sense, then why the previous version of v1.27.5 is working fine?
Where does the keyword of somp_thr came from? I couldn't find it anywhere.

[viarotel]

I won't close this question for now, you're the only one reporting this problem, but I do need more details like how to quickly reproduce the issue, since it works fine on my device.

To isolate the issue, I have tested to manually run gnirehtet run with the platform-tools (adb), from both of the version and it was success.
So the gnirehtet and adb itself has no problem.
Somehow Escrcpy failed to execute the wrapped command in the newer version.

---

After the somp_thr error, there was a leftover of gnirehtet.exe process not being killed.
With process explorer I could see that it has the command line of relay
So the command gnirehtet.exe relay is successfully executed by Escrcpy.
The error of somp_thr cames after that.

---

It turns out the port occupied error is caused if I click the Gnirehtet more than once.
If gnirehtet.exe relay is previously not running, then there will be no port occupied error.

The difference from v1.27.5 from v1.27.6 on the file of electron/exposes/gnirehtet/index.js is the commit of 0e098c3.
Not sure what causes it.

P.S. The phone OS is Nougat 7.1 API 25 if that matters.
