Hello i find out that is when i save this image with .jpeg. And use jsreport to show it. It's cause the error.

Gabriel Dehner:
I changed the "Content-Type: application / json"

Hello, can u tell me exactly where u change ? I have the same issue.

hello.

I have a config file as below. How can i set limit request handling. Example 3 request per seconds. Or 3 request in queue ?

{
"httpPort": 5488,
"reportTimeout": 600000,
"enableRequestReportTimeout":true,
"certificate": {
"key": "cert.key",
"cert": "cert.crt"
},
"logger": {
"console": { "transport": "console", "level": "error" }
},
"allowLocalFilesAccess": true,
"store": {
"provider": "memory"
},
"blobStorage": {
"provider": "memory"
},
"templatingEngines": {
"numberOfWorkers" : 8,
"strategy": "http-server"
},
"extensions": {
"authentication": {
"cookieSession": {
"secret": "dainb@0986301253@cenTos",
"cookie": {
"secure": true
}
},
"admin": {
"username": "admin",
"password": "jsreport@5488"
},
"enabled": true
},
"chrome-pdf": {
"timeout": 600000,
"strategy": "chrome-pool",
"numberOfWorkers": 8
}
}
}

We push in html around 500-700kb. Thank you. I can handle from there.

OK so do u have any comment about max request jsreport can handle or something ?
Is it related to CPU or RAM ?

Hello.
I was trying to deploy jsreport in Docker.
https://drive.google.com/file/d/17OXnn7hso-1RfwZcHa_LbVDgzEuzANSX/view?usp=sharing

Deployment file config in the link.
The problem is :
When a large amount of requests are sent to my server (pod) running jsreport. The request is stuck, the log is stopped. And no more requests can be processed.

My system:
2.2ghz, SSD
Scale 2 pods. Limited to 6 CPU cores, up to 16 GB ram.

What can I do to optimize the smooth running?

I can accept some tweaks in the configuration for the best. I'm not asking you to simulate the problem. Please help me.

OK. Now i understand that pkg not resolve my problem.

I tried to download this one (https://github.com/jsreport/jsreport/releases) but it cant start. When i open it open command line window and shutdown (exit) imediately. Is that any special in there ?

Hello.
I create jsreport to generate PDF is OK now.
I use PKG npm newest version to create EXE file that run a jsreport server.
with command: pkg server.js

server.js

const jsreport = require('jsreport')()
const fs = require('fs')
if (process.env.JSREPORT_CLI) {
  // export jsreport instance to make it possible to use jsreport-cli
  module.exports = jsreport
} else {
  jsreport.init().then(() => {
    // running
  }).catch((e) => {
    // error during startup
    console.error(e.stack)
    fs.writeFileSync("log.txt", e.stack)
    process.exit(1)
  })
}    

jsreport.config.json

{
"httpPort": 5488,
"store": {
	"provider": "memory"
},
"blobStorage": {
	"provider": "memory"
},
"logger": {
	"console": {
		"transport": "console",
		"level": "debug"
	}
},
"allowLocalFilesAccess": true,
"reportTimeout": 600000,
"templatingEngines": {
	"numberOfWorkers": 4,
	"strategy": "http-server"
},
"chrome": {
	"launchOptions": {
		"args": []
	}
},
"extensions": {
	"authentication": {
		"cookieSession": {
			"secret": "secret_string"
		},
		"admin": {
			"username": "admin",
			"password": "jsreport"
		},
		"enabled": true
	},
	"scripts": {
		"strategy": "http-server"
	}
}
}

The problem is it's ok to start.

In the image:
1 -> successful init
2 -> error i got when create PDF with server running by file created by PKG
(with server running by node server.js its OK)

Anyone have an experiment about this issue ?
