htmlMetaDescription Errors (Blank or #value!)

Hi and thanks for your help.

I am new to this and need your help.
I was trying to get the htmlMetaDescription but as the title suggests, comes up as either empty or #value!

Also when I did this, I also got this error and kept having to dismiss it

Hi Nick, did you include the http:// part of the URL? If so, please provide the URL which caused this error.

hi,

I have used all three. Http://www, https://www, http://
https://www.lambda.energy
http://www.aquayield.com
http://afpltd.net/

There is blanks

For
http://www.touchdynamic.com
http://www.mainstream-global.com
http://thinlabs.com
http://www.softiron.com

There is #value! error

https://www.lambda.energy is not using a meta description.

I get a valid response for http://www.touchdynamic.com
