I have been using html-pdf (phantomjs) for creating PDF on AWS Lambda with NodeJS 8.0 and it was working fine. Since AWS Lambda has stopped support on NodeJS 8.0 we have updated our NodeJS version to the latest 12.x and we are now getting the following error when we run out PDF Lambda function:
{"errorType":"Error","errorMessage":"write EPIPE","code":"EPIPE","errno":"EPIPE","syscall":"write","stack":["Error: write EPIPE"," at afterWriteDispatched (internal/stream_base_commons.js:154:25)"," at writeGeneric (internal/stream_base_commons.js:145:3)"," at Socket._writeGeneric (net.js:784:11)"," at Socket._write (net.js:796:8)"," at doWrite (_stream_writable.js:403:12)"," at writeOrBuffer (_stream_writable.js:387:5)"," at Socket.Writable.write (_stream_writable.js:318:11)"," at PDF.PdfExec [as exec] (/var/task/node_modules/html-pdf/lib/pdf.js:141:15)"," at PDF.PdfToBuffer [as toBuffer] (/var/task/node_modules/html-pdf/lib/pdf.js:44:8)"," at /var/task/index.js:121:38"]}
phantomPath: './phantomjs_lambda/phantomjs'
process.env.FONTCONFIG_PATH='/var/task/fonts'
I tried to check similar issues in StackOverflow. I have pointed the phantomjs path correctly, also have the fontconfig in place. We are now stuck as we are unable to update the Lambda function. Any help will be highly appreciated.
Update: Changed the path to phantomjs binary:
phantomPath: './node_modules/phantomjs-prebuilt/lib/phantom/bin/phantomjs'
After changing the path to phantomjs binary, the error has changed to:
{"errorType":"Error","errorMessage":"write EPIPE","code":"EPIPE","errno":"EPIPE","syscall":"write","stack":["Error: write EPIPE"," at WriteWrap.onWriteComplete [as oncomplete] (internal/stream_base_commons.js:92:16)"]}
I recently face this issue as well, when i have update Node version of lambda to 14.x. After following below steps i can able to resolved my issue.
I passed phantomPath : "./node_modules/phantomjs-prebuilt/lib/phantom/bin/phantomjs" at pdf.create(html,tempParamms)
.so files and paste them in your project root.fonts in your project root..so files and paste all files in newly created fonts directory.fonts/fonts.conf.FONTCONFIG_PATH with value = /var/task/fontsfonts/fonts.conf
<?xml version="1.0"?>

You are getting this Error because AWS pull out basic utilities in the environment from node 10.x to 12.x (eg ImageMagick).
The solution is to either include the missing functionality your self or use lambda layers. Here is information on lambda layers with ImageMagic https://github.com/serverlesspub/imagemagick-aws-lambda-2
For further reading on this problem I suggest looking into the AWS forum here: https://forums.aws.amazon.com/thread.jspa?threadID=305691
html-pdf use a npm package phantomjs-prebuilt
phantomjs-prebuilt will automatically install phantomjs for you based on your OS/Archritecture
It's important that the node_modules doesn't get copied over to the docker image And rather get installed on the docker image itself
I have created custom docker image for azure, for AWS you would need to do the same https://docs.aws.amazon.com/lambda/latest/dg/images-create.html
Following the this thread you would need to install a couple of dependencies as well https://gist.github.com/julionc/7476620
Ensure you have node_modules/ in your .dockerignore file
node_modules/
Docker file for azure functions (Should create simular dockerfile for AWS lambdas)
FROM mcr.microsoft.com/azure-functions/node:3.0-node12-appservice
RUN apt-get update
RUN apt-get install build-essential chrpath libssl-dev libxft-dev -y
RUN apt-get install libfreetype6 libfreetype6-dev -y
RUN apt-get install libfontconfig1 libfontconfig1-dev -y
ENV AzureWebJobsScriptRoot=/home/site/wwwroot \
AzureFunctionsJobHost__Logging__Console__IsEnabled=true \
OPENSSL_CONF=/etc/ssl/
COPY . /home/site/wwwroot
RUN cd /home/site/wwwroot && \
npm install
Adding the OPENSS_CONF=/etc/ssl/ is essential as phantomjs will throw another error
