Hey there - could you please let us know which lab this is?
Looks like this is Careers in Cybersecurity / Penetration Tester.
You can disregard the error message. As long as you scroll back up, you should see the expected result (i.e. confirmation that the hash algorithm is MD5).
Yes, this is under Careers in Cybersecurity / Penetration Tester.
I figured it out. Thank you
