IndexError in aider/coders/base_coder.py when running 'aider' command

[CSi-CJ]

When asking questions or reporting issues, it is very helpful if you can include: Install with pip3 install git+https://github.com/paul-gauthier/aider.git@azure

• Aider version 0.8.2
• Model being used gpt-4
• Other switches or config settings that are active

The easiest way to do this is just just copy & paste the announcement lines that aider prints when you launch it, like these:

aider 0.8.2
Model: gpt-4
Git repo: .git with 134 files
Repo-map: basic using 1024 tokens (ctags executable not found)
Use /help to see in-chat commands, run with --help to see cmd line args

Error: IndexError in aider/coders/base_coder.py

Description

When running the aider command, I encountered the following error:

Traceback (most recent call last):
File "/usr/local/bin/aider", line 8, in <module>
sys.exit(main())
File "/usr/local/lib/python3.8/dist-packages/aider/main.py", line 398, in main
coder.run()
File "/usr/local/lib/python3.8/dist-packages/aider/coders/base_coder.py", line 383, in run
new_user_message = self.run_loop()
File "/usr/local/lib/python3.8/dist-packages/aider/coders/base_coder.py", line 456, in run_loop
return self.send_new_user_message(inp)
File "/usr/local/lib/python3.8/dist-packages/aider/coders/base_coder.py", line 488, in send_new_user_message
interrupted = self.send(messages, functions=self.functions)
File "/usr/local/lib/python3.8/dist-packages/aider/coders/base_coder.py", line 652, in send
self.show_send_output_stream(completion, silent)
File "/usr/local/lib/python3.8/dist-packages/aider/coders/base_coder.py", line 728, in show_send_output_stream
if chunk.choices[0].finish_reason == "length":
IndexError: list index out of range

This error occurs when trying to access the finish_reason property of the first element in the chunk.choices list, but the list is empty or does not have a first element.

Steps to Reproduce

1. Install the aider package using pip: pip install aider
2. Run the aider command with java file
3. chat with java file "help me xxxxxx"
4. Observe the IndexError

Expected Behavior

The aider command should run without any errors and provide the expected functionality.

Additional Information

I tried to let aider check the log specification of my java code, but I always reported this error.

Any assistance in debugging and fixing this issue would be greatly appreciated.

Thanks for trying aider and filing this issue.

Is there a reason you installed aider with that very specific pip install command? You installed a very old branch of aider directly from github.

Normally you should just do git install aider-chat per the install instructions:
