@hep99_twitter

That's worked. Thanks so much. Does the node_modules have to be in the jsreport folder or can it look in the main node_modules at the root of the project?

Hey Everyone, I am using JSreport for production and it is deployed in Heroku with 1x dyno
But app keep crashing when 11 concurrent requests are made. I am unable to figure out what is the root issue

I am using the default jsreport.config.json

{
  "extensions": {
  "httpPort": 5488,
  "httpsPort": null,
  "store": {
    "provider": "fs"
  },

  },

        "--no-sandbox"
      ]
    }
  }
}

can someone help me with the configuration

BJR Matos

@bjrmatos

hi @gauravprwl14

hmm the configuration file looks wrong, it should be more like this:

{
  "httpPort": 5488,
  "httpsPort": null,
  "store": {
    "provider": "fs"
  },
  "blobStorage": {
    "provider": "fs"
  },
  "logger": {
    "console": {
      "transport": "console",
      "level": "debug"
    },
    "file": {
      "transport": "file",
      "level": "info",
      "filename": "logs/reporter.log"
    },
    "error": {
      "transport": "file",
      "level": "error",
      "filename": "logs/error.log"
    }
  },
  "allowLocalFilesAccess": true,
  "templatingEngines": {
    "timeout": 10000,
    "numberOfWorkers": 12,
    "strategy": "http-server",
    "templateCache": {
      "max": 100,
      "enabled": true
    }
  },
  "extensions": {
    "chrome": {
      "timeout": 40000,
      "strategy": "chrome-pool",
      "numberOfWorkers": 12,
      "launchOptions": {
        "args": [
          "--no-sandbox"
        ]
      }
    }
  }
}

however i don’t know if this is the real file you are using or you just copied it wrong here

as per the 11 concurrent requests problem hmm i don’t have a good explanation, it will be really weird the jsreport produces this alone, i guess this is a problem with some configuration in Heroku, are there no logs available in the Heroku side?

or maybe there are also some jsreport logs that you can share when does request are made, if it breaks at jsreport side you should be able to get some logs in logs/error.log

Hi, I'm trying to use PDFUtils to add a footer using a docker image of jsReports and an azure app that remotely accesses the docker image. I'm using this code.

HttpContext.JsReportFeature()
.Recipe(Recipe.ChromePdf)
.Engine(Engine.Handlebars)
.Configure((r) => r.Template.Chrome = new Chrome {
Format = "A4"
})
.Configure((r) =>
{
r.Template.PdfOperations = new[]
{
new PdfOperation()
{
Template = new Template
{
Content = strHeaderFooterHtml,
Engine = Engine.None,
Recipe = Recipe.ChromePdf,
Chrome = new Chrome {Format = "A4"}
},
Type = PdfOperationType.Merge
},
new PdfOperation()
{
Template = new Template
{
Content = strCoverHtml,
Engine = Engine.None,
Recipe = Recipe.ChromePdf,
Chrome = new Chrome {Format = "A4"}
},
Type = PdfOperationType.Prepend
}
};

});

the standard header footer from https://playground.jsreport.net/w/admin/kMI4FBmw

but I see this rendered on the page.. {{#each $pdf.pages}}{{#if @index}}

I pass the HTML for header/footer as a string of the actual html

Jan Blaha

@pofider

when you set Engine = Engine.None, then no engine is used tags like {{#each}} will just stay as strings

you likely want to use Engine.Handlebars for the header merge operation

Cleadon

@hep99_twitter

of course... thanks

Cleadon

@hep99_twitter

I'm getting a strange error. Passing the helpers in as a string from..

new PdfOperation()
{
Template = new Template
{
Content = strHeaderFooterHtml,
Helpers = strHeaderFooterHelper,
Engine = Engine.Handlebars,
Recipe = Recipe.ChromePdf,
Chrome = new Chrome {Format = "A4"}
},
Type = PdfOperationType.Merge
}

gives An unhandled exception has occurred while executing the request.
Error while executing pdf-utils operations. Error while executing templating engine. Unexpected token 'return'

the string is

function getPageNumber (pageIndex) {
if (pageIndex == null) {
return ''
}

const pageNumber = pageIndex + 1

return pageNumber

}

function getTotalPages (pages) {
if (!pages) {
return ''
}

return pages.length

}

Jan Blaha

@pofider

please use here code highlighting, it is otherwise hard to read

https://github.com/adam-p/markdown-here/wiki/Markdown-Cheatsheet#code

otherwise the string looks good, not sure what is the problem, maybe some wrong escaping

Cleadon

@hep99_twitter

thanks, will make sure all code in highlighted in future

You were right, now working

Is it better to post in here or on the Forums? I already posted my question on the forum (https://forum.jsreport.net/topic/1665/jsreport-types-missing) but i am not sure which is monitored more

Jan Blaha

@pofider

Hi, I answer on forum

Hi... I am trying to access the $pdf object in my handlebars template so that I can write conditional logic for the PDF header based on the pageNumber..... but I am unable to manage to get the $pdf variable working... it probably seems to stay undefined... I tried different ways but I am not able to make it work... PLEASE SOMEONE KINDLY HELP ME..

I'm sorry but I am a bit lost in your question. Please try to reformulate it and elaborate more

Hello friends. I've updated from 2.6 to 2.10. I've set up a header/footer and use the options in studio to merge them. Then I set up toc to be merged in an afterRender function. This was working fine in 2.6. In 2.10, this breaks my page numbers in the toc. If I merge the toc via studio, it works as expected. I can't seem to tell why

@pofider

Could you do a minimal zip with export that replicates this and upload it somewhere?
