Cannot open project UnhandledPromiseRejectionWarning

[cryptax]

I am trying to open a project, it fails and shows errors in console.

This is running inside a Docker container which contains Android SDK + Android Emulators + NodeJS + Frida + Dexcalibur, (why? because I am trying to build such a container for people with Windows, for which Dexcalibur doesn't seem to install ok).

• Docker container
• Ubuntu 20.04.1 LTS
• Dexcalibur 0.7.5
• Frida 14.2.13
• NodeJS 12.20.2
• Android emulator 11 x86_64 with google apis

hi,

It is same issue than #42

I cannot reproduce the issue but i fixed a potential platform issue with 5942fa0a9b130a404485cd898c9e1b4e125fe25c.

Please retry with v0.7.6 (now available on NPM).

[duckness]

currently facing the same problem. I'm running Android 11/API 30 but don't notice it here

is it related?

Tried with both 0.7.5 and 0.7.6

[FrenchYeti]

@duckness Can you check the content of folders inside "<DEXCALIBUR_WORKSPACE>/.dxc/api/sdk_androidapi_29_google" ? Since you run Dexcalibur on Windows, this error can have a different root cause.

Is the stack trace is similar ? => Error in synchronizePlatform()

after looking at the stacktrace a bit closer, I realised that the very first run (on 0.7.5) gave me that exact error:

TypeError: Cannot read property 'getUID' of undefined
    at DexcaliburProject.fullscan (C:\Users\duckness\Downloads\dexcalibur-master\dexcalibur-master\src\DexcaliburProject.js:712:56)

    at processTicksAndRejections (internal/process/task_queues.js:93:5)

subsequent runs on 0.7.5 and 0.7.6 gave me a slightly different error, instead of undefined, it is null. I have been unable to reproduce the undefined:

[FrenchYeti]

Very good information :)

As i cannot reproduce the error, can you patch your code with the commit dbba59a557b1489d7175d39bdeeeb81a1932b2c9 ?

Can you say me if an error occurs and if there are more error messages into terminal ?

Thanks !

EDIT: Only src/PlatformManager.js and src/WebServer.jsshould be patched.

[duckness]

[ERROR] Platform Manager : undefined is not a valid platform

I get this and nothing else

[FrenchYeti]

@cryptax can you check if v0.7.8 solves your issue ?

[FrenchYeti]

I close this issue. Feel free to update this issue, if problem persists.

[cryptax]

Just tried. The problem persists with 0.7.8.

Would you like me to join my Dockerfile to help you reproduce?

[cryptax]

By the way, I am getting the same error, even without using a Dockerfile, i.e straight on the host. Version 0.7.8. Can you re-open the bug?

Did you select a device for the project ? Is this devices is successfully enrolled ?
Is it an emulator or a physical device ?

[cryptax]

• yes the device is enrolled
• it is an emulator. Actually an ARM7 emulator. But I don't think it is related to ARM or x86.

[cryptax]

With more tests, note this error only happens at the creation of the project. Actually, the project gets created, so, if after that you choose to open an existing project, it works, and you manage to open and analyze the APK.
