I seem to have found the wrong place, vm2 3.9.18 does not have the Contextify method, so how to solve this problem, is it to directly rewrite the place where the Contextify method is used in jsreport-core\lib\render\safeSandbox? @thomaskotze

\jsreport-core\lib\render\safeSandbox.js:110:48
Error when processing render request 1 Cannot read properties of undefined (reading 'Contextify') TypeError: Cannot read properties of undefined (reading ' Contextify')

If it is convenient, post a piece of code (because the API calls are the same, I can quickly locate the location), or tell me the approximate path of this thing, because I really did not find this thing, thank you @thomaskotze

I searched the entire program and there is no such parameter @thomaskotze

This is how I call the render method in jsreport-core, the following config is the incoming template.

jsreport.render({ template: template, data: renderData })

{
    "name": "name",
    "shortid": "11111111111111",
    "$entitySet": "templates",
    "engine": "handlebars",
    "recipe": "chrome-pdf",
    "folder": {

    },

    },

        {
            "type": "merge",
            "templateShortid": "SpotTpCover",
            "renderForEveryPage": false,
            "mergeWholeDocument": true,
            "mergeToFront": true
        },
        {
            "type": "merge",
            "templateShortid": "header_footer",
            "renderForEveryPage": false,
            "mergeWholeDocument": true,
            "mergeToFront": true
        }
    ]
}

rendertemplateconfig.json, I did not use the parameter pdfPassword in it, it seems that this is not the problem, thank you for your timely reply. @thomaskotze

Can you provide a keyword, I didn't find any of these three @thomaskotze

Hi Jan,

I saw in this thread (https://forum.jsreport.net/topic/2810/new-version-of-jsreport-v2-to-fix-the-vm2-issue) that the dependency of jsreport-core can be upgraded to solve the security problem of vm2, but jsreport-core will not work after I upgrade vm2 to 3.9.18

The specific error location is jsreport-core/lib/render/render.js await reporter.beforeRenderListeners.fire(request, response) , after this method reports an error, the following will directly enter the catch and return an empty, resulting in the PDF cannot be exported, so at this time how should i solve this problem

ok, thanks for your reply.

This is the html I copied under temp before merging to PDF. From here you can see that I used my own font, so the font of win and linux should be the same.

When using compare-pdf to compare two PDFs, the differences will be highlighted, such as the green part in the figure.

The position of the fonts generated by win and linux is a little bit different, which leads to this problem.
