Project in Eclipse not finding javax.servlet.* with open liberty

Question

I'm trying to run a java project with open liberty, but the servlet API is not being found.

• I'm using the WebSphere Application Server Liberty Profile v8.5 server and its pointing to a valid open liberty instance.
  2. In the project facets Dynamic Web Module is selected & WebSphere Application Server Liberty Profile is checked.

What is missing?

Update

Here is some extra info.

Java 1.8
OL 21.0.0.11
myeclipse 2020.9.16
