Modifying the Config doesn't work.

[MarquisT]

I have followed the instructions and when I use your lambda.zip file it seems to work. But when I update the config to change the image sizes, it fails. I have used the npm install and ./bundle.sh to create the zip. I then tear down the CloudFormation and the Lambda and start again. It creates the new lambda correction but it doesn't work. When I look at the log file I get:

Can you show the me config you use? maybe the JSON is invalid?

The issue was actually with the nodes_module. For some reason when I follow the instructions and run the install npm, then bundle it, it creates a separate directory for each required bundle (async, gm, array-parallel, array-series, etc). Your script seems to require array-parallel, array-series, etc to be in the nodes_module directory inside the gm directory of the root nodes_module directory. When I move them there manually, the script works. Any idea why they need to be there? And why install puts them in the subfolders?

I guess that's related to the node version. Can you run those two commands to get the node and npm version:

npm -v
node -v

ALso, what Operating System are you using?

[MarquisT]

npm -v 3.10.9
node -v v6.9.2

I'm using a Mac.

Okay, that's similar to my setup.

Just to understand the problem correctly. Can you post the output of the following command tree -L 1 node_modules/ before you move directories (this should not work) and after (this should work).

First of all, thank you @michaelwittig for your example.

I had same issue. The lambda.zip file wasn't updated for years, but it worked and helped me to resolve the issue. I discovered that with my npm 3.10.10 doesn't get dependencies for gm module. There was no node_modules/gm/node_modules folder. After I run nvm install 0.10.36 && nvm use 0.10.36, I can use bundle.sh to package lambda.
