Image optimization in Custom Print formats

ERPNext
1

We are a business based in India, registered under GST, and have to generate E-Invoice. I was able to get all the data I need and display most elements in a custom invoice format. The place where this keeps breaking is when I add the img tag as shown below

<img src="data:image/png;base64,{{ SignedQRCodeImg }}" class="qrcode">

On saving the template, erpnext gives the following error

and changes my email template to this

<img src="/files/AXwCN8t.png" class="qrcode">

What I also notice is that it, tries to create a file and attach it to this print format. As seen in the updates section and attachments section of the print format doc

Ohhh God! Found the fix here

Replaced the entire image src and updated it like shown in the abovelink

{% set SignedQRCodeImgSRC = "data:image/png;base64," + get_qr_code(SignedQRCode,scale=2) %} <!-- Image can be placed here --> <img src={{SignedQRCodeImgSRC}} class="qrcode">
