Module development and code questions

Hello good!

I need help with a problem that we have detected on the website of one of our clients (escofet.com).

I am a fresher here to Drupal, and my problem statement is as follows:
There is an existing Drupal code (.info and .module files only in repo), which needs to be promoted to Drupal9 which will contain .info.yml file, I have tried to manipulate existing one, but it throws error saying "Missing 'application'" which is added in my dependencies in .yml file. I am attaching screenshots for reference and looking forward for some dedicated support please to fix this error.

Hello,

I am currently trying to build a simple module that calls a Javascript function to ask for a users location data, (lat and long). Then take those two variables and send it back to a function inside of my moduleservice.php file. What would be the best way of doing this, or is my approach improper?

Thanks

Hi Everyone,

I am trying to access all the links in the Breadcrumb outside the preprocess function. Seen many posts and examples regarding removing or adding them in a service. So far nothing that helps in getting only the links. Anyone have a suggestion?

Hello Team,

I am trying to create a custom form with format "basic_html". With this I can see Rich Text editor. When i am trying to get the HTML tags in form submit i can get only text . 

  $form['body'] = [
      '#type' => 'text_format',
      '#format' => 'basic_html',
      '#allowed_formats' => ['basic_html'], 
      '#required' => TRUE,
      ];
 
In form Submit :

    $body = $form_state->getValue('body')['value'];

$body does not return HTML tags from editor

Please help me with this issue.
