Steps to reproduce

I started dify version 0.6.15 with docker. I set the environment variable for the code node. Run the following command to check the environment variables of the sanbox container:

The code of Code Execution Node 1 is as follows:

def main() -> dict:
    original_strings_with_empty = ["apple", "", "cherry", "date", "", "fig", "grape", "honeydew", "kiwi", "", "mango", "nectarine", "orange", "papaya", "quince", "raspberry", "strawberry", "tangerine", "ugli fruit", "vanilla bean", "watermelon", "xigua", "yellow passionfruit", "zucchini"] * 5


    extended_strings = []

    for s in original_strings_with_empty:
        if s: 
            repeat_times = 600
            extended_s = (s * repeat_times)[:3000]
            extended_strings.append(extended_s)
        else:
            extended_strings.append(s) 
    
    return {
        "result": extended_strings,
    }

And then I run the app. The app crashes. The error message is as follows:

Run failed: Node Code Execution run failed: Failed to parse result

Then I change the code of Code Execution Node 1 to set the character length to 2000.

def main() -> dict:
    original_strings_with_empty = ["apple", "", "cherry", "date", "", "fig", "grape", "honeydew", "kiwi", "", "mango", "nectarine", "orange", "papaya", "quince", "raspberry", "strawberry", "tangerine", "ugli fruit", "vanilla bean", "watermelon", "xigua", "yellow passionfruit", "zucchini"] * 5


    extended_strings = []

    for s in original_strings_with_empty:
        if s:  
            repeat_times = 600

            extended_s = (s * repeat_times)[:2000]
            extended_strings.append(extended_s)
        else:

            extended_strings.append(s) 
    
    return {
        "result": extended_strings,
    }

The application is running properly.

Then I change the code of Code Execution Node 1 to make the original_strings_with_empty have less elements.

def main() -> list:
    original_strings_with_empty = ["apple", "", "cherry", "date", "", "fig", "grape", "honeydew", "kiwi", "", "mango", "nectarine", "orange", "papaya"] * 5

    extended_strings = []

    for s in original_strings_with_empty:
        if s:  
            repeat_times = 600
            extended_s = (s * repeat_times)[:3000]
            extended_strings.append(extended_s)
        else:
            extended_strings.append(s) 
    
    return {
        "result": extended_strings,
    }

The application is also running properly.

According to my understanding, I have configured the environment variables correctly, but the application still reports an error. It cannot handle a string array with more than 3000 elements per string.

✔️ Expected Behavior

The application is running properly.

❌ Actual Behavior

Run failed: Node Code Execution run failed: Failed to parse result

The error message "Run failed: Node 代码执行 run failed: Failed to parse result" when handling a string array with more than 3000 elements per string is likely due to the limitations in the code execution environment of the Dify app. Despite configuring the environment variables, the code execution environment has specific constraints on the size of data structures, including string arrays.

The environment variables CODE_MAX_STRING_LENGTH and CODE_MAX_STRING_ARRAY_LENGTH are set to limit the maximum length of a string and the maximum number of strings in an array, respectively. Specifically, CODE_MAX_STRING_LENGTH is set to 80000 characters, and CODE_MAX_STRING_ARRAY_LENGTH is set to 300000 elements. However, the actual execution environment may still impose practical limits that cause the code to fail when these limits are approached.

To resolve this issue, you should consider breaking down your string array into smaller chunks that comply with the environment's limitations. This can be done by processing the array in smaller segments and then combining the results as needed. Here is an example of how you might handle this in Python:

def process_large_array(large_array):
    chunk_size = 1000  # Define a chunk size that is manageable
    results = []
    
    for i in range(0, len(large_array), chunk_size):
        chunk = large_array[i:i + chunk_size]
        # Process each chunk
        result = process_chunk(chunk)
        results.append(result)
    
    # Combine results if necessary
    final_result = combine_results(results)
    return final_result

def process_chunk(chunk):
    # Your processing logic here
    return chunk

def combine_results(results):
    # Logic to combine results
    return results

By processing the array in smaller chunks, you can avoid hitting the resource limits of the sandboxed environment and prevent the app from crashing ^[1]^[2]^[3]^[4].

Could you take a look at this one @Yeuoly

In the template_transformer.py file of the dify source code, there is a function named extract_result_str_from_response. Debugging the code that triggers the Run failed: Node Code Execution run failed: Failed to parse result error. It is found that the input parameter response format of extract_result_str_from_response is incorrect.

The incorrect response is as follows:

As you can see, the content of the response variable is not complete, there is no << RESULT >> at the end, and the content of "result": is also incomplete.

The content of the response variable is obtained by the following statement response = post(str(url), json=data, headers=headers, timeout=CODE_EXECUTION_TIMEOUT)

I run the preceding test code in the dify-sandbox-1 container. The code is all working fine. So I think that maybe the POST request is truncated.

Thanks for reporting this, it looks like the response content is incomplete, I will check it soon, or have you already got any idea of how to fix it?

I haven't found the root cause yet, why truncation is triggered. I don’t know if it’s due to Nginx or post or the dify code bug.

A few words to add, the following code sometimes triggers an error, and sometimes it doesn’t. This is also very magical.

def main() -> dict:
    original_strings_with_empty = ["apple", "", "cherry", "date", "", "fig", "grape", "honeydew", "kiwi", "", "mango", "nectarine", "orange", "papaya", "quince", "raspberry", "strawberry", "tangerine", "ugli fruit", "vanilla bean", "watermelon", "xigua", "yellow passionfruit", "zucchini"] * 5


    extended_strings = []

    for s in original_strings_with_empty:
        if s: 
            repeat_times = 600
            extended_s = (s * repeat_times)[:3000]
            extended_strings.append(extended_s)
        else:
            extended_strings.append(s) 
    
    return {
        "result": extended_strings,
    }

I also reproduced this bug using the online version of dify official website

I have reproduced it successfully, but not only this, I also encountered an operation not permitted error, I guess it should be a memory optimization issue, will fix it soon in 0.2.5.

@Yeuoly Thanks a lot. Looking forward to the next version

When will the update to version 0.2.5 be released? @Yeuoly

@majestichou I solved it, and your test case has been added to CI, thanks so much for your contributions!
