I’m stuck on Stage #EA6

The output is exactly what it wants. It just doesnt work, i have spent way to long on this so i hope you guys can explain this.

Here are my logs:

```auto
[compile] Moved ./.codecrafters/run.sh → ./your_program.sh
[compile] Compilation successful.
Debug = true
[tester::#EA6] Running tests for Stage #EA6 (Scanning: Lexical errors)

[tester::#EA6] [test-1] Writing contents to ./test.lox:

[your_program] [line 1]: Error: Unexpected character: @
[your_program] EOF null

[tester::#EA6] [test-1] Expected line #1 on stderr to be "[line 1] Error: Unexpected character: @", but didn't find line
[tester::#EA6] [test-1] Test failed

```

Output of manual test:

```auto
[line 1]: Error: Unexpected character: @
EOF null

```

Hey @bjoernp116, error messages should be printed to **stderr** , but it seems they’re currently being printed to **stdout**.

Let me know if you’d like further clarification.
