Fix clw-prompt-oom: OpenClaw Prompt Memory Exhaustion Error

Fri, 07 Aug 2026 05:32:04 +0800

1. Symptoms

The clw-prompt-oom error occurs when the input prompt submitted to OpenClaw exceeds the configured or system-imposed memory allocation for prompt processing. Users encounter this error during normal operations when attempting to process large text inputs, batch operations, or complex multi-line prompts that consume more memory than the application has available or is willing to allocate.

The characteristic shell output when this error manifests typically appears as follows:

[ERROR] clw-prompt-oom: Prompt input exceeds available memory allocation
        Prompt size: 45.2 MB
        Available memory: 32.0 MB
        Suggestion: Reduce prompt size or increase memory limit

In interactive mode, the error presents with additional context about the current session state:

Fix clw-prompt-failure: Resolving OpenClaw Interactive Prompt Failures

Thu, 30 Jul 2026 03:08:04 +0800

1. Symptoms

The clw-prompt-failure error manifests when OpenClaw’s command-line interface cannot successfully display, receive, or process interactive prompts from the user. This error surfaces during operations that require user confirmation, configuration input, or selection from interactive menus.

Typical shell output includes:

[ERROR] clw-prompt-failure: Interactive prompt failed to display
Prompt type: confirmation
Timeout: 30s
Error: EPROMPT001 - Prompt session terminated unexpectedly

[ERROR] clw-prompt-failure: Unable to receive user input
Prompt: "Enter configuration value for 'cluster-name'"
Error: Input stream closed or unavailable

[ERROR] clw-prompt-failure: Prompt validation failed
Provided input: "<empty>"
Validation rule: required, non-empty string
Error: EPROMPT002 - Input validation unsuccessful

Fix ValueError: Python ValueError Exception Handling and Prevention

Mon, 20 Jul 2026 17:32:04 +0800

1. Symptoms

Python’s ValueError manifests when a function receives an argument with the correct type but an inappropriate value. This exception signals that the argument value itself violates expected constraints, unlike TypeError which indicates wrong types entirely. Developers encounter this error during data conversion, input validation, mathematical operations, and string parsing operations.

Common shell output patterns include:

Traceback (most recent call last):
  File "script.py", line 15, in <module>
    result = int("42.5")
ValueError: invalid literal for int() with base 10: '42.5'

Traceback (most recent call last):
  File "data_processor.py", line 42, in parse_date
    date_obj = datetime.strptime(date_string, format)
  File "/usr/lib/python3.11/_strptime.py", line 555, in _strptime.py", line 555, in _strptime
    raise ValueError(f"unconverted data remains: {data}")
ValueError: unconverted data remains: +05:00

Traceback (most recent call last):
  File "calculator.py", line 8, in calculate
    result = math.sqrt(-1)
ValueError: math domain error

These tracebacks consistently identify the offending line, the function involved, and the specific value that violated the expected constraints. The error message provides context about what went wrong, such as “math domain error” for negative square root attempts or “invalid literal” for string-to-integer conversion failures.
