Contact for Enquiry Form is not working for SP Property component

This is for Joomla 4.

In the "contact" function of this file /com_spproperty/controllers/agents.php , it is not able to get the values of the variables like $name, $email, $recipient, etc. This is the main cause of the issue. Please fix it for Joomla 4, and update the component so that we could download and install.

I have included the login details (tested and confirmed working) with this reply.

By the way, if you had read my original analysis above, I even pointed you which file has issues. You could simply put the quickstart on a Joomla 4 installation, and replicate the issue, and fix it, rather than asking me for my login.
Anyways, I have provided you with the login. Please check.

The contact form at the bottom of https://delicacyhome.com/index.php/agents/1-john-anderson page is still not working.

Now, this page stopped working:

It seems to be okay if we change the map to Google Maps. But it is not working if we change the map to Open Street Map.

I need it to work using Open Street Map. Could you please check why?

May I know what the issue was?
