I want to fetch data from database in table but it show me undefined variable error in view using compact

error:

my controller

The error message "Undefined variable: users" indicates that the $users variable is not being passed correctly to the view. The issue might be related to the way you are using the compact function in your controller.

Ensure that the requests table exists in your database and contains data.
Check if you have imported the DB facade at the top of your controller file. 

Verify that you have properly defined the showHospital view and it is located in the correct directory.

Double-check the syntax of the compact function and make sure you are passing the variable correctly. The code you provided seems to be correct, but it’s worth checking for any typos or inconsistencies. Ensure that you’re passing the correct variable name ($users) as the argument to compact.
