Unable to invoke method in default app about cocaine-framework-python HOT 3 CLOSED

Okay, let the debug begins :)

First of all, you can enable debug output to see what exactly happens with cocaine. To do this, open cocaine-runtime's config (the same file you pointed with -c or --config option when cocaine-runtime started) and find logging configuration block. You need to rewrite it like this:

"loggers": {
  "core" : {
    "type" : "files",
    "args" : {
      "path" : "/dev/stdout",
      "verbosity" : "debug"
    }
  }
}

Now, cocaine-runtime will print all log output to the stdout. Just run it: cocaine-runtime -c [CONFIG_FILE] and post here what it prints when you execute service.enqueue('doIt', 'SomeMessage').get(). Sometimes everything becomes clear at this point.

Also you can enable python-framework's debuging output by specifying it directly via python standard logging module:

import logging
log = logging.getLogger('cocaine')
log.setLevel(logging.DEBUG)

...

service.enqueue('doIt', 'SomeMessage').get()

By the way, when you are executing cocaine-tool call command, it has the following signature: cocaine-tool call APP [METHOD] [ARGS]. To see echo app methods just type cocaine-tool call echo and you will see:

Service provides following API:
 - info
 - enqueue

See, there is no method 'doIt' - it is just an event name - the first parameter for enqueue's method. So right command is: cocaine-tool call Echo enqueue "'doIt', 'SomeMessage'".

Thanks. Debug info was very helpful. I uploaded app with wrong path in manifest.json. I tried re-upload application and manifest, restarted, but it still use old valued, that was in manifest.json before i fixed it. Then i uploaded this app with new name - it worked like charm.

Apps are cached locally, that's why re-uploading doesn't change anything. If you use Process as your isolate plugin (which is the default), then simply remove the cache section from the configuration file to disable app caching.
