Creating a lambda function in AWS from zip file
I am trying to create a simple lambda function, and I’m running into an error.
My code is basically
console.log('Loading function'); exports.handler = function(event, context) { console.log('value1 =', event.key1); console.log('value2 =', event.key2); console.log('value3 =', event.key3); context.succeed(event.key1); // Echo back the first key value // context.fail('Something went wrong'); }
in a helloworld.js file. I zip that up and upload it as a zip file in the creating a lambda function section, and I keep getting this error:
{ "errorMessage": "Cannot find module 'index'", "errorType": "Error", "stackTrace": [ "Function.Module._resolveFilename (module.js:338:15)", "Function.Module._load (module.js:280:25)", "Module.require (module.js:364:17)", "require (module.js:380:17)" ] }
Anyone have any ideas?
Answer
The name of your file needs to match the module name in the Handler configuration. In this case, your Handler should be set to helloworld.handler
, where helloworld
is the file that would be require()’d and handler
is the exported function. Then it should work with the same zip file.
