Fix clw-prompt-timeout: OpenClaw CLI Prompt Timeout Error

Mon, 10 Aug 2026 05:32:04 +0800

1. Symptoms

The clw-prompt-timeout error manifests when running OpenClaw CLI commands that require interactive user input. The application waits for a response from the terminal, but no input arrives before the configured deadline expires, causing the operation to abort with a timeout error. Users typically encounter this error during authentication flows, configuration initialization, or when the CLI attempts to prompt for confirmations or selections in non-interactive environments.

When this error occurs, the CLI outputs a message similar to the following:

Fix clw-prompt-unreachable: Prompt Response Unreachable Error

Thu, 06 Aug 2026 03:08:04 +0800

1. Symptoms

The clw-prompt-unreachable error manifests when OpenClaw attempts to solicit user input through its prompt system but cannot establish or maintain the necessary communication channel. Users encounter this error in several distinct scenarios that share a common underlying theme: the prompt mechanism fails to reach the user or receive their response.

Shell Output Examples:

[OpenClaw] Error: clw-prompt-unreachable
Message: Unable to reach prompt destination. stdin may be closed or redirected.
Suggestion: Ensure terminal is attached and stdin is available.

Error Code: clw-prompt-unreachable
Context: interactive_prompt
Terminal State: detached

Error: clw-prompt-unreachable: Prompt response channel unreachable
   at PromptChannel.connect (prompt.ts:142)
   at InteractiveSession.requestInput (session.ts:89)
   at ClawCLI.promptUser (claw-cli.ts:203)

When this error occurs, the application typically aborts the current operation rather than timing out or proceeding with default values. The process exits with a non-zero status code, usually 1 or a custom error code defined by the OpenClaw implementation. In scripted environments where OpenClaw runs non-interactively, this error can cause pipeline failures or unexpected termination of dependent processes.

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 clw-prompt-invalid: Invalid Prompt Configuration in OpenClaw CLI

Sat, 30 May 2026 12:44:04 +0800

1. Symptoms

When executing OpenClaw commands, you may encounter the clw-prompt-invalid error with various manifestations depending on the nature of the invalid prompt configuration. The error typically appears immediately after running a command that relies on prompt templates or user input scaffolding.

Common symptoms include:

Command execution halts with exit code 1 and no further action is taken
Error message displays immediately after invoking any command that uses prompt interpolation
Partial output may appear before the error is thrown, showing a truncated stack trace
The CLI becomes unresponsive or fails to initialize the prompt engine

A typical error message looks like this:
