Polly not working after Core upgrade to WP 5.6.1

[mnmedia]

Hi,
the AWS for WordPress plugin stopped working creating audio files after the WP Core was updated from 5.6.0 to 5.6.1
The audio player is still visible, but there is no audio created in the S3 bucket.
The only changes to the website were twofold:

1. Automatic core update to 5.6.1
2. SSL advanced settings through .htaccess (however those have been reversed and do not seem to play a role)

Could you please check to compatibility of WP 5.6.1 and AWS Polly and make the necessary changes in the plugin is needed.

I have tested the following possible sources of issues:

1. deactivated all lexicons -> no change
2. created simple test article (to test if something in the affected article was blocking audio creation) -> no change, also test article with NO audio
3. deactivating and reactivating text-to-speech

I cannot downgrade to 5.6.0 at present, since the site runs on a multisite network and this would affect more sites.

Support will be greatly appreciated. Thank you.

Appendix: The following code is rendered

<div id="amazon-ai-player-container">
<audio class="amazon-ai-player" id="amazon-ai-player" preload="none" controls   controlsList="nodownload" >
<source type="audio/mpeg" src=""></audio>
		</div>
<div id="amazon-polly-subscribe-tab"></div>
<div id="amazon-polly-by-tab"></div>

So, there is also no audio link created (empty src="")

Hi,
I’ve got the same issue with the empty tag.
When I debugged it, in the log file I get the following issue

[05-Mar-2021 09:12:29 UTC] PHP Notice: Trying to get property 'ID' of non-object in /opt/bitnami/apps/wordpress/htdocs/wp-content/plugins/amazon-polly/public/class-amazonpolly-public.php on line 112

As my programming skills end with the content of the log file, I would like to ask if anyone could assist.
Any help will be appreciated
Thanks in advance
