Phantom-pdf report rendering of data of 16MB

virajitha.3112

Hi,
Good morning
I am trying to render report using phantom-pdf for 16MB data.
with phantom-pdf using "dedicated-process" and
"templatingEngines": {
"strategy": "http-server",
"numberOfWorkers": 4,
"forkOptions": {
"execArgv": ["--max-old-space-size=6096"]
}
}
I am getting this error:
2020-05-21T19:27:19.729Z - debug: Base url not specified, skipping its injection.

and with phantom-pdf set to "http-server", I get EConnreset error. I have used time out as 100 minutes
I have gone through your forums where it mentions about using these options to improve performance. But both the options are failing for me.
Can you please guide me here?
Thank you very much.

It looks phantomjs crashes after 5 minutes without an error reported to jsreport.
It could be out of memory problem. How many pages do you expect to be rendered?

Do you get this working with chrome-pdf recipe?

The html file that is generated at c:\users.....\autocleanup folder has 48MB size. The pdf file has around 3000 pages with each record data something like this: divided into 6 columns
5/13/2020 4:00:00AM 5/13/2020 4:00:00AM 1 Generating PDF 6.178.63.58 End Point Mapper

I have tried chrome-pdf also. I am sending request using postman with response time and data set to "0". That is no limit. In JSReport server I donot see any error and neither do i get response on post man.

It just stops here.

I am using the default chrome-pdf settings in jsreport config.
Please help us with this or give some pointers or directions as we are not bale to process records above > 20MB.
