When you are trying to start the Managed server using weblogic management REST API , sometimes you get Internal Server Error but the server will be started though.
Issue snippet:

Solution
The solution is very simple, Just make sure you are using the correct header values. Especially the Host. I had to update the Host Header value to localhost:17001 from localhost and that fixed my issue.
here is the successful request Snippet
