AI invented a nonexistent debugging function three times in a row

A developer asked an AI to debug code, and it repeatedly hallucinated a function that does not exist.

• The first suggestion sounded plausible and matched the library’s naming conventions, but the function was fake.
• After being corrected, the model apologized and offered another equally confident but still nonexistent function.
• On the third try, it produced a fully detailed example for a function it had invented on the spot.
• The poster gave up and went back to reading the real docs, joking that confidence and correctness seem inversely related.
