Viewsaws-lambda Cannot find module
I keep getting this error in the aws-lambda console when uploading code from a zip file. I have tried uploading other zip files and they work correctly. The .js file is named "CreateThumbnail.js" in the zip file. I believe the handler is also named properly "CreateThumbnail.handler". the node_modules subdirectory is also setup. Anyone have any idea?
{
"errorMessage": "Cannot find module 'CreateThumbnail'",
"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)"
]
}

The way I was able to get this to work was:
- Name the file exports.js
- Name the handler, within the file, exports.handler
- Set the handler in the lambda config to exports.handler
- Zip up only the contents of the folder, not the folder itself (as mentioned above) and rename the zip file exports.zip

Ok, I did this myself, just make sure that you make the zip such that the .js file doesn't end up inside a folder, because AWS would unzip the file you upload and tries to find a .js file by the name of handler you gave, and if its inside a folder it won't help you.

One possible problem is if you upload the lambda as a zip file created via PowerShell Compress-Archive. Compress-Archive has a bug which causes AWS to extract the files into a flat tree (no subdirectories), with backslashes in filenames:
