Hello,

I have fixed the warning. Please review MR.

Thanks

#6 it's great thank you

yoast_seo 1.8
I set the metatag async module on the mange form page

I type in a character into the title field and I get the following js errors:

yoast_seo.js?v=1.x:294 Uncaught TypeError: Cannot read properties of null (reading 'value')
at YoastSEO_DrupalSource.renewData (yoast_seo.js?v=1.x:294:74)
YoastSEO_DrupalSource.renewData @ yoast_seo.js?v=1.x:294

yoast_seo.js?v=1.x:286 Uncaught TypeError: Cannot set properties of null (setting 'value')
at yoast_seo.js?v=1.x:286:71
(anonymous) @ yoast_seo.js?v=1.x:286
setTimeout (async)
YoastSEO_DrupalSource.renewData @ yoast_seo.js?v=1.x:284

The same error does not show up when I do not use the metatag async module

Created temporary patch from MR in #6 🐛 Add compatibility with Metatag Asynchronous Widget Needs work .
