There is an appendAfterPageNumber option to append in the middle.

append(sourcePdfBuf, appendedPdfBuf, options)
parameters:

- sourcePdfBuf -> pdf buffer to which to append the second param
- appendedPdfBuf -> pdf buffer appended after source
- options -> (optional)
options.appendAfterPageNumber -> the number of page from sourcePdfBuf which the pages from appendedPdfBuf should be inserted after

If you need to insert content in the middle of the page, you need to use the merge.

I am not sure what your helpers pdfMerge and merge and pdfRaw do, but there is no way to embed another pdf directly from the html and templating engines. What you need to do is to invoke pdf utils from the afterRender script and use jsreport.pdfUtils.append to dynamically assemble multiple pdfs together.

Does this mean that you are replacing the dependency of the deprecated module azure-storage with the successor Azure Storage Blob client library for JavaScript?

Yes

What is the expected release date and is there a beta for testing available?

You can use dep @jsreport/jsreport-fs-store-azure-storage-persistence@4.1.0

To help you, please elaborate more... Do you have some specific configs? Every template doesn't run? What if you use the "Run now" button schedule, does it run? What if you set the schedule minute interval like this, does it run?

Could you provide output logs?

Would you be able to share the repo replicating the problem?

In general, you can install the font to the OS, or use a webfont from cdn, or embed font in base64

If the height of the component is fixed, then this demo should work for you

The support for managed identity will be part of the next release.

What is the idea of that dot . ? That is likely the problem.

{{component (filePath  ../lib ../cid ../ver) . dynamicData="ABCDDDDDDDD"}}

In handlebars, when you want to use a helper to calculate the attribute of another helper, you use () subexpressions.

{{docxImage src=(barcodeHerper "qrcode" data.invoiceNumber)}}

Please finalize the demo. You are missing those components/helpers there...
