[DEPRECATED] Undefined is not an object evaluating register_handler_fx

Deprecation note

This type of error should not occur anymore now that we require the namespace in the fx.cljs file.

It can however happen with other macros requiring a cljs namespace.

The general fix for that type of issue is to have two files for the namespace where your macros are defined, let's say for my-project.my-macro namespace you would have:

• my_macro.cljs in which you need (:require-macros my-project.my-macro) and (:require my-project.the-namespace-used-in-the-macro)
• my_macro.clj in which you define the macro

That way you don't need to use any magical call like find-ns or inline require with some kind of call only once switch (which was the root cause of another bug in defstyle macro because the compilation phase at which the evaluation of the switch is done was not properly considered).

You also want to make sure users are using the macro by using a aliased namespace defined in require statement rather than require-macro and refer to the macro directly. Otherwise it won't require the cljs file and the require statement of the namespace in the macroexpension might not be there.

Cause

• stacktrace mentions register_handler_fx,
• common cause is when requires have been cleaned up and a require of status-im.utils.handlers namespace was removed because it looked like it was unused but was actually used through a fx/defn macro

Solution

go through known faulty commit looking for deleted requires

Git "unable to access" errors during yarn install

Description

Developer updates package.json file with a new dependency using a GitHub URL. So it looks like this:

  "react-native-status-keycard": "git+https://github.com/status-im/react-native-status-keycard.git#feature/exportKeyWithPath",

Afterwards, when running e.g. make run-metro, they might see the following confusing error:

# macOS
fatal: unable to access 'https://github.com/siphiuel/react-native-status-keycard.git/': SSL certificate problem: unable to get local issuer certificate
# Linux
fatal: unable to access 'https://github.com/status-im/react-native-status-keycard.git/': Could not resolve host: github.com
info Visit https://yarnpkg.com/en/docs/cli/install for documentation about this command.

Cause

yarn.lock is not updated to be in sync with package.json.

Solution

Update yarn.lock file. In order to do this, perform the following steps on a clean status-react repo:

cd status-react
yarn install

and don't forget to commit updated yarn.lock together with package.json.

adb server/client version mismatch errors

Description

Running some adb commands, e.g. adb devices or make android-ports (in turn invokes adb reverse/adb forward commands) may display the following message:

adb server version (40) doesn't match this client (41); killing...

or the reverse

adb server version (41) doesn't match this client (40); killing...

This might cause all kinds of difficult-to-debug errors, e.g.:

• not being able to find the device through adb devices
• make run-android throwing com.android.builder.testing.api.DeviceException: com.android.ddmlib.InstallException: device 'device-id' not found.
• make run-android throwing - Error: Command failed: ./gradlew app:installDebug -PreactNativeDevServerPort=8081 Unable to install /status-react/android/app/build/outputs/apk/debug/app-debug.apk com.android.ddmlib.InstallException: EOF
• dropped CLJS repl connections (that have been enabled previously with the help of make android-ports)

Cause

System's local adb and Nix's adb differ. As adb include of server/client processes, this can cause subtle version errors that cause adb to kill mismatching server processes.

Solution

Always use respective make commands, e.g. make android-ports, make android-devices, etc.

Alternatively, run adb commands only from make shell TARGET=android shell. Don't forget the TARGET=android env var setting - otherwise adb will still be selected from the system's default location. You can double-check this by running which adb.
