JS Report Studio doesn't render reports, but can do it with api



  • Hi,

    I have installed JSReport on my local machine. I use it to render some reports of my web application. Everything work fine. But when I try to create new report with Studio and render it, I get this error: Error: read ECONNRESET
    at TCP.onStreamRead (internal/stream_base_commons.js:209:20)

    I reimported my reports with the import utility in Studio. The error is still there.

    I use Windows 10 64 bits Pro and JS Report 2.11.0 (cli version 2.2.5) with NodeJS 14.8.0

    Thanks



  • Please share the jsreport output logs for the start.

    I believe this error isn't the last one but from somewhere before?

    2021-12-06T11:27:35.751Z - error: Error when processing render request 32 Unsupported asset encoding param value utf-8, supported values are base64, utf8, 
    link, dataURI and string Error: Unsupported asset encoding param value utf-8, supported values are base64, utf8, link, dataURI and string                  
    

    Unfortunately, the output isn't very explaining...

    read ECONNRESET
    logs:
    +724    Rendering engine handlebars using http-server strategy
    +1152   Rendering request 1 finished with error in 1152 ms
    Error: read ECONNRESET
    

    This just says that you are evaluating handlebars and there is a heavy unhandled crash of nodejs process.
    Would you be able to email me your workspace so I can import it and take a quick look?



  • I think that the problem is somewhere in the own report. I send data to report to fill the fields. I added the below script to each report to receive this data:

    async function beforeRender(req, res) {
      req.data = Object.assign({}, req.data, { template: req.template, options: req.options })
    }
    

    So, in my report, I access those variables as it (example):

            <!--{{ setLocale options.language }}-->
    
    {{ toUpperCaseFirstLetter $localizedResource.from}} : {{ formatTime startDate @root.options.language }}
    

    where setLocale and toUpperCaseFirstLetter are JS functions defined in the report scripts just below the main report window. That is probably what is caused bug while rendering it from Studio.

    The question now is, how can I continue to show my report in Studio while keeping this setup?

    Any idea is welcome



  • Maybe you search for this:

    async function beforeRender(req, res) {
      req.options.language =  req.options.language || req.template.resources.defaultLanguage || 'en'
      req.data = Object.assign({}, req.data, { template: req.template, options: req.options })
    }
    

    The req.template.resources.defaultLanguage is actually something you fill in the studio UI.



  • I try to run reports on my other computer with Windows 10 Pro 64 bits, but with Node 12.14.1 and JSReport 2.6.1. Everything works fine in Studio. I exported those reports and imported them in the server who has problem and got still the same error message. Seem to be a bug with Node and/or JSReport or a missing Node module. I will try to reinstall the same Node and JSReport versions of my other computer.

    When you told me to email you my workspace, what do you mean exactly? Is the export reports?

    Thanks



  • I reinstalled on my machine NodeJS 12.14.1 Windows 64 bits (exactly what I have on my other machine) and try to install JS Report 2.6.1. But infortunatly, I could really just install the latest release with npm. So I installed JS Report 3.0.0. I both try Studio and my web application with my report and everything works fine. So, it is a bug with Node JS 14.

    For the moment, I resolved the problem. Could you tell me where I should open a ticket about this bug? And what do you need to reproduce the bug? If you want, I can email you my reports.

    I wait your instructions

    Thanks



  • To make it the easiest for us, please compress the whole application folder of the crashing app.
    Upload it to some onedrive,dropbox... and send me the link. I would check what's wrong and then you can remove it.
