SWE-agent for coding challenge fails to write patch due to Syntax Error
Describe the bug
SWE-agent works for running hello world tutorial but running the SWE-agent for coding challenges results in syntax error. This syntax error appears to prevent writing to a file so no patch is made.
If I run the same command again immediately after a second time, I get a different error but seems related (E999 Syntax error) except this appears it will loop until all funds in my openai account run out. The command I am running twice is (4.) below in steps to reproduce
first run see the code generated at:
🎬 ACTION
edit 4:4
second run see E999 error.
I thought it could be due to '\n' in the generated code instead of \r\n like this bug; but, I am unsure and I do not have any good ideas at the moment.
Any suggestion would be appreciated as I am stuck.
Steps/commands/code to Reproduce
- Followed installation instructions from source and set openai key in .env file
- Successfully ran hello world tutorial
- Error happens when running the tutorial Using SWE-agent for coding challenges
- command used removed the "--actions.apply_patch_locally=True" from the tutorial because patch isn't being generated, I assume from the error below. Added --env.repo.type="local" --problem_statement.type="text_file" but with or without these two error does not change
$ sweagent run --config config/coding_challenge.yaml --problem_statement.path="[path to]/problem.md" --env.repo.path=[path to code challenge] --agent.model.name="gpt-4o" --agent.model.per_instance_cost_limit 3.0 --env.repo.type="local" --problem_statement.type="text_file"
- execute 4. twice. the first run and second run output below. second run is manually interrupted because it seemed to keep looping over the syntax error "E999 SyntaxError: unexpected character after line continuation character"
Error message/results
First Run
see attached FirstRun.debug.log for full log. I spelled "firstMissingPositive" from the tutorial but, I can see I did that wrong. I can't see what else is wrong.
Let's proceed by implementing the `firstMissingPositive` method to solve the problem. We'll ensure the solution runs in O(n) time and uses O(1) auxiliary space. The approach typically involves using
the array itself to record the presence of numbers by marking indices.
I'll start by correcting the method name and implementing the solution.

def firstMissingPositive(self, nums: List[int]) -> int:
n = len(nums)

while 1 <= nums[i] <= n and nums[nums[i] - 1] != nums[i]:

for i in range(n):
if nums[i] != i + 1:
return i + 1
return n + 1

Ah, it looks like the coding_challenge config is a bit outdated. In particular, it doesn't use function calling. I probably can only look at that on Wednesday or later, but if you wanna play with it, take the anthropic_filemap.yaml config (which is the default), and modify it a bit to be similar to the coding_challenge config and it should work.
I think there might be a bug in the non-function calling parsing of the edit action (we also use a slightly different one now by default).
Wow, thanks for such a quick response :) ! I will attempt to follow your directions and if I am successful I will report back.
Following your directions, in the coding_challenge.yaml I changed:
parse_function: type: thought_action
to:
parse_function: type: function_calling
and as far as I could tell it worked. It populated the function definition, made the tests and saved to disk (after I added .--actions.apply_patch_locally=True back to my command)
I only started playing with this code base today so I do not understand if, and I doubt, this correctly updates coding_challenge.yaml.
To me updating the coding_challenge.yaml should/would be a separate specific ticket, if as you mentioned it is out of date.
So you have helped solved my issue so I will close this ticket and keep exploring this excellent project.
Great! Let me keep this open though (I might close it for another later but just so I don't forget), because it technically should also work with the thought_action parsing, so there seems to be some problem here somewhere.
Thanks again for the issue and all!
From my trajectory file, I get the following output: https://gist.github.com/rambip/91c1947757099e96fa3c9cfafe978d86
I don't know if insert and then a text is supposed to be a correct output. I also don't know how the text is supposed to be formatted / escaped.
The model uses """ to escape a text that contains itself """. I'm not sure it's the cause of the problem, but that's a bug too.
