title: I cannot edit http files or use the http client on IntelliJ, how can I resolve this?
body: <p>I am trying to learn Spring Boot and as part of this I need to send http requests to test the functionality of the API I have created.</p>
  <p>When following along with <a href="https://youtu.be/9SGDpanrc8U?t=3958" rel="nofollow noreferrer">this video</a>, the teacher had an 'actions for URL' selection which I do not see in my own editor. Note that the point in the video I linked shows this.</p>
  <p>After updating (to IDEA 2021.1) and restarting I still could not see this option.</p>
  <p>I tried to create my own .http file, but am <a href="https://i.stack.imgur.com/3DbpH.png" rel="nofollow noreferrer">not able to work with this type of file</a>.</p>
  <p>After more research I found that I should have a plugin called 'http client' installed by default. I cannot find this in my installed plugins or by searching through the marketplace.</p>
  <p>When downloading and installing manually (from <a href="https://plugins.jetbrains.com/plugin/13121-http-client" rel="nofollow noreferrer">here</a>), I now get <a href="https://i.stack.imgur.com/q3oFg.png" rel="nofollow noreferrer">this error</a> which I cannot resolve.</p>
  <p>Please can someone give me a pointer to get this plugin working.</p>
