  It seems you use jsreport.exe binary and it can't run chrome.exe for some unknown reason.
  The chrome.exe is extracted to the user temp during the first run.

  Please try to remove the [user temp folder]/jsreport and try it again.
  Typically its here c:\Users\[user]\AppData\Local\Temp\jsreport\

  As you can see, for the string array I had to force quotation marks and commas, but after that, everything worked great!

  There are some string chars that can break your code. Therefore toJS helper is recommended.

  As always, you guys are right on the money with your solutions. Can't thank you guys enough, and I'm certain I'll have more. :-)

  You are more than welcome.

  XLSX odd error

  I apologize for not mentioning the actual typo. You got it right then.

  {{#xlsxReplace "xl/styles.xml"}} {#asset style.xml} {{/xlsxReplace}}

  This is actually older v2 syntax. Its still compatible with v3, but now we use the following
  https://jsreport.net/learn/assets

  {{#xlsxReplace "xl/styles.xml"}} {{asset "style.xml"}} {{/xlsxReplace}}

  However, virtually identical files with the extra curly bracket will also work.
  It also does not explain why the same file was working locally but not on the test server

  I have tried replicating the issue and getting some hypotheses why it works for you on one server and not on the other, but unfortunately, I don't know.

  Since as of nov 12 2021 unoconv is deprecated. Its not a speed issue, more of a consern security-vice to be able to have the newer version that atleast have recent changes and are still being maintaned. Not sure if there are any added functionality. Would be nice to see where this upgrade is on the roadmap of jsreport.

  Thank you for the fast reply, great support as always for a great product!

  Thanks so much for the quick response! The fix you recommended worked beautifully, and thanks for explaining the differences between v2 and v3 and how it handles the helpers.

  Hahaha! Your reply is almost the same as I can expect. However, it is reasonable. The security issue can not be just ignored due to code check tool. I can try to use "overrides" of NPM to upgrade vm2 directly. Maybe we could upgrade to Jsreport V3 as well later.
  Thank you! Have a nice day! @jan_blaha

  change the name of the pdf file

  @Ish-Modi it all depends on the pdf viewer you use, in the studio we use the standard pdf viewer which has the limitation I described.

  in your app, you don't need to use the same pdf viewer, although it is handy to let the browser handle the preview, it will have the same limitation. instead, you can check other pdf viewers which allow this customization. I think pdf.js is one of those that don't have this problem and will let you have a download button with a custom name. another solution is to add to your app a custom download button that triggers download from jsreport-client.

  How to use each loop in header pdf util

  hi @Happy-Patel

  it looks your code is the right way, there are multiple ways you can simplify it, one way is that instead of adding pdf page item per property value, you just use a single call with all the properties. then in the header you are sure your data is in the 0 index, and can create just a single function for all your properties access.

  if you need to conditionally render something based on the avatar you can still do it in the header, from the main you can just propagate the avatar value (without the if) no matter if it is undefined or not

  here is a demo

  As you suggested using the pkg tool it is hard to create an exe file, can you provide an alternative way to achieve my requirements?

  Thanks @bjrmatos26 in advance for your time and help.

  Clone sheet and populate data

  I see yes.
  The thing is that in this case, the sheet includes references to other files that you need to clone as well.
  For example, the filters are defined in the xl/tables xmls. So you need to clone this as well and update the references.
  I know its tedious work, but we don't have API that could do this for you at this moment.
  You gonna need to unzip the xlsx and check the references in worksheets/sheet*.xml and clone the references xmls as well.

  Syncing Errors using Azure Blob Storage

  I apologize. I've read the docs now and the maximum leaseDuration in azure is 60s which is the default. So we can't change this. Please skip the lock options.

  If the other configs won't help. Please check if you have the storage in the same Azure region as the app.
  Also azure provides low-latency premium storage, maybe it will work faster and eliminate the problem.
  Another option is to map some file system azure provides and use plain jsreport fs store.

  The prefix config is now supported in @jsreport/jsreport-fs-store-aws-s3-persistence 3.1.0

  "fs-store-aws-s3-persistence": { "bucket": "...", "accessKeyId": "...", "secretAccessKey": "...", "prefix": "someBucketInFolder" .... }

  Thanks for the example and reply. Turns out, we were still using 3.6.2 and while it had the component feature in the UI, i think it was maybe buggy. As soon as I updated to 3.11.3, passing parameters works as documented. Posting this just in case anyone else runs into it. Should have known to upgrade to latest before trying a new feature!

  xlxs template - cell data-type is not defined by Excell
  • bstornext

  This is defined in the cell s attribute which is a reference to the styles.xml.

  <row> <c s="1"><v>11</v></c> </row>

  You can either find out the right s value in an existing xlsx template you use or use xlsx helpers to update the styles.xml. Like here

  https://playground.jsreport.net/w/anon/nOIQZfMt

  {{#xlsxAdd "xl/worksheets/sheet1.xml" "worksheet.sheetData[0].row"}} <row> <c s="1"><v>11</v></c> </row> {{/xlsxAdd}} {{#xlsxReplace "xl/styles.xml" "styleSheet.cellXfs"}} <cellXfs count="2"> <xf numFmtId="0" fontId="0" fillId="0" borderId="0" xfId="0"/> <xf numFmtId="2" fontId="0" fillId="0" borderId="0" xfId="0" applyNumberFormat="1"/> </cellXfs> {{/xlsxReplace}} {{{xlsxPrint}}}

  As always with xlsx transformations, it requires you to check how the XML structure looks like inside existing xlsx files and replicate the same with xlsx helpers.
