QR code is not generated in the config form

I've tested this on fresh Drupal 10 setup and couldn't reproduce. It works as designed.

Need more details on your module and drupal version and steps to reproduce.

Tested this on module version 2.0.8
Drupal version 10.2.8
PHP version 8.1

I have the same problem. Without the image tag the raw png data is printed.
data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAA.....
The patch fixes this for me.

Module version: 2.0.8
Drupal: 10.1.4
PHP: 8.1

Again, the issue is not reproducable to me, Checked on fresh drupal installation. The code

`$authenticator->getQr()` returns svg structure, your patch is wrong svg structure cannot be put into < img src="[svg_code_here]" >.

The issue is not reproducable in the first place. Both of you try reinstalling the module.

@ahmed, it looks like you're expecting an svg, but I'm getting a png. What kind of image toolkit and settings are you using? PNG does work here < img src="[encoded_png_code_here]" >, which is why this patch works for me. Thanks.

I've updated the module to the latest version, and reinstalled it. Core is now 10.2.4.

Here is one extra solution that will work with both types of generated qr-code encoding png to base64 and svg.

Fixed 2 type qr codes display patch

@awolfey In my case, the situation is worse. Locally, I have SVG, on the server, I have PNG. Based on that, I've created patch #14

Hi all,

I have successfully replicated the issue and for solving it, applied the patch attached in #14 .

This patch successfully fixed the QR code generation issue. I'm attaching here the screenshots of the config form before and after applying the patch respectively.

Along with that, I've converted the patch as MR also.

Thanks !

Those facing this issue, update the module to latest version.

@blade_ukraine, thanks for the patch its merged.
