Openwhisk: Request Entity Too Large - openwhisk

Question

I have a local docker-based setup of Apache Openwhisk (https://github.com/apache/incubator-openwhisk-devtools), and when I'm trying to create an action from of a zip containing a packaged nodejs app with
wsk -i action create test --kind nodejs:6 test.zip -v
I get the following response:
413 Request Entity Too Large
The test.zip is only 5 MB large. What causes this issue? Is there any way to make openwhisk process larger requests?
UPD: the content of the test.zip is generated from a nodejs project, which has only 1 .js, which has a simple kafka topic consumer functionality.
function main(params) {
var kafka = require('kafka-node');
var HighLevelConsumer = kafka.HighLevelConsumer;
var Client = kafka.Client;
if (!(params && params.host)) {
return {error: 'host is required'};
}
if (!(params && params.port)) {
return {error: 'port is required'};
}
if (!(params && params.topic)) {
return {error: 'topic is required'};
}
var host = params.host;
var port = params.port;
var topic = params.topic;
var client = new Client(`${host}:${port}`);
var topics = [{
topic: topic
}];
var options = {
autoCommit: true,
fetchMaxWaitMs: 1000,
fetchMaxBytes: 1024 * 1024,
encoding: 'utf8'
};
var consumer = new HighLevelConsumer(client, topics, options);
consumer.on('message', function(message) {
console.log(message.value);
});
consumer.on('error', function(err) {
console.log('error', err);
});
process.on('SIGINT', function() {
consumer.close(true, function() {
process.exit();
});
});
}
exports.main = main;
And the package.json is the following:
{
"name": "test",
"version": "1.0.0",
"description": "",
"main": "test.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1",
"start": "node test.js"
},
"author": "",
"license": "ISC",
"dependencies": {
"kafka-node": "^2.6.1"
}
}
It works correctly if I simply run it with npm start.

It looks like the NGINX proxy used to expose the API interface for the OpenWhisk platform defaults to a small value for the maximum request body size.
I have managed to re-produce the issue locally, anything above 512KB returns that error.
I've opened a ticket to see if the default limit can be increased: https://github.com/apache/incubator-openwhisk-devtools/issues/124
