App crash when trying to close shell

[bodaghialib4]

hi,

I am using react-native-ssh-sftp as an ssh shell. It works fine. But when I try to close the ssh shell, my app crash.
I get the below logs from adb logcat command.

RNSSHClient: Error starting shell: Stream closed
AndroidRuntime: FATAL EXCEPTION: Thread-19
AndroidRuntime: Process: com.remotefilemanager, PID: 10904
AndroidRuntime: java.lang.RuntimeException: Illegal callback invocation from native module. This callback type only permits a single invocation from native code.
AndroidRuntime: 	at com.facebook.react.bridge.CallbackImpl.invoke(CallbackImpl.java:25)
AndroidRuntime: 	at com.reactlibrary.RNSshClientModule$3.run(RNSshClientModule.java:200)
AndroidRuntime: 	at java.lang.Thread.run(Thread.java:919)
ActivityTaskManager:   Force finishing activity com.remotefilemanager/.MainActivity

It seems that the callback of startShell invoked more than one time. first when the shell started correctly and then when I closed the shell and got the error in reading from the stream(BufferedReader).

Please help me to fix this problem.

my testing enviroment information:

• platform: android 10 (emulator)
• react: "16.9.0"
• react-native: "0.61.5"
• react-native-ssh-sftp: "^1.0.3",

Hi, I also encountered this problem, please tell me if your problem is solved?

I have the same problem, have you solved it and can you tell me the solution?

I could not find a good solution. But I found the cause of the error.

when we try to close the shell, in line 186 it gets an error and try/catch trying to handle it. but it causes calling callback.invoke() two times.

so for a temporary solution, after installing liberary, I remove callback.invoke(error.getMessage()); in catch parts (lines 197&200 in RNSshClientModule.java of liberary).
but I need to repeat it after any yarn command.

dear @shaqian,
could you please fix this?
