@jan_blaha : Amazing. It works. I should have posted this query much earlier, spent 2 days in digging out why it's crashing. Thanks again a ton. :)

I am trying to add two pages before TOC- say 'title page' and 'disclaimer' page.

The final merged PDF should look like [title, disclaimer, toc, main]

The approach I am taking is:
I am adding {{{pdfAddPageItem pageBeforeTOC=true}}} on both title and disclaimer template which has to appear before toc.

//disclaimer template
<p><BR><BR><BR><BR><BR><BR><BR><BR><BR><BR><BR><BR><BR><BR><BR><BR></p>
{{{pdfAddPageItem pageBeforeTOC=true}}} <p>This is Disclaimer Page</p>

//Title page template
<p><BR><BR><BR><BR><BR><BR><BR><BR><BR><BR><BR><BR><BR><BR><BR><BR></p>
{{{pdfAddPageItem pageBeforeTOC=true}}} <p>This is Title Page</p>

And in toc, I am adding empty pages using helper function:

{{#each (getPagesBeforeTOC @root)}}
    <!-- in order to produce a new page there must be some element before -->
    <div style="visibility: hidden;">&nbsp;</div>
    <div style="page-break-before: always;"></div>
{{/each}}

However, this is crashing:

Error: Error while executing pdf-utils operations. incorrect header check
    at module.exports (/app/node_modules/jsreport-core/lib/util/createError.js:11:13)
    at Reporter.createError (/app/node_modules/jsreport-core/lib/reporter.js:332:12)

caused by: Error: incorrect header check
    at Zlib.zlibOnError [as onerror] (zlib.js:180:17)
    at processChunkSync (zlib.js:426:12)

Any help is appreciated.

Here is the narrowest version of the replicator:

Please note, If I add only one page before TOC, then it works perfectly without any problem. You can check this by disabling any of the title or disclaimer items in the main pdf-utils merge operation.

In most of the use cases, to create any report "multiple pages with the headers footers+page number" are required to prepend before TOC. Hence, I am looking for a robust solution for this, if my approach above is not the correct one.

Thanks.

Thanks, I got the idea now and was able to implement without need to script here using jsreport.documentStore.collection and pdfutils.

Resolving

Here is the example by admin that creates a clickable TOC in chrome.

I tried replicating the same by using the script instead of pdfutils, however, this does not seem to work.

Can someone please help me?
