Hi Sowmiya,

Any Updates ?

It is very urgent for us.

Hi Ranjit, 

Thank you for your patience. 

At present, we do not have direct support for converting HTML to PDF in AWS environment. Our converter requires some dependencies packages for converting HTML to PDF in AWS, currently we do not have commands to install those dependencies packages in AWS environment. However, we can convert the HTML to PDF document by using Docker container with AWS, here, we can add those dependencies packages in a docker file.  

Please refer to this below link for converting HTML to PDF in Linux docker container.

Hi Sowmiya,

I had tried your suggestion but getting an error. Could you please provide us a sample lambda function ?

{
"errorMessage": "RequestId: c35a198e-2380-4e2d-ad37-1e617c5143c0 Error: Couldn't find valid bootstrap(s): [AWSLambda2::AWSLambda2:Function::FunctionHandler]",
"errorType": "Runtime.InvalidEntrypoint"
}

Hi Ranjit, 

 

Thank you for your update. 

 

As we said earlier, we do not have direct support for converting HTML to PDF in AWS Lambda function. Our converter requires some dependencies packages for converting HTML to PDF in AWS Lambda, currently we do not have commands to install those dependencies packages in AWS environment, it does not work in AWS Lambda function. We have asked raised a query about dependencies installation in AWS forum. Once we got or find any solution to install the packages, we will let us know the details in this forum.  

 

However, we did not face this type of error “Couldn't find valid bootstrap(s): Runtime.InvalidEntrypoint” before on our end and we suspect that the error raise from AWS runtime. Can you please share the sample which you are facing this error, or steps to replicate this on our end.  

 

Currently, we have sample for converting Html to PDF using Linux docker container and we will deploy the sample in AWS environment and provide the details on February 23rd 2021.

Hi Gowthamraj,

Sorry for late reply, I was busy on some other stuff. 

I have fixed  “Couldn't find valid bootstrap(s): Runtime.InvalidEntrypoint” issue, it occurs due to .Net version mismatch but still not able to generate html to pdf file.
