On this page

First, match MISSING_CREDENTIAL

This page targets MISSING_CREDENTIAL. The full message can contain a few extra words on different operating systems or Node.js versions, but the core error code or phrase should match.

MISSING_CREDENTIAL
missing credential
DSH MISSING_CREDENTIAL

When searching or asking for help, copy the full error and remove API keys, private repository names, usernames and sensitive paths.

Fast fix: MISSING_CREDENTIAL

For normal setup, open Settings → Models and save the API key on the provider card. If the provider uses apiKeyEnv, set that exact environment-variable name before starting DSH; use the command for your operating system below.

What MISSING_CREDENTIAL means

DSH knows which provider or model the session wants to use, but it cannot find a usable credential for that provider.

Common causes of MISSING_CREDENTIAL

  • No API key has been saved for the selected provider.
  • The session still points to a provider whose credential was removed.
  • apiKeyEnv names an environment variable that was not set before DSH started.
  • You edited a different DSH profile from the one that is currently running.

Fix MISSING_CREDENTIAL

  1. 01

    Check which provider the session uses

    Read the selected model and the error details. Confirm whether the session uses the built-in DeepSeek provider or a custom OpenAI-compatible provider.

  2. 02

    Save the key in the Web UI

    Open Settings → Models, edit the matching provider, enter the key in its credential field and save. For the normal provider-card flow, you do not need an environment variable.

  3. 03

    Only use environment commands when apiKeyEnv is configured

    The variable name must exactly match apiKeyEnv. GATEWAY_API_KEY below is an example; replace it with the name in your provider configuration.

  4. 04

    Windows PowerShell

    Set the variable in the same PowerShell window that will start DSH.

    $env:GATEWAY_API_KEY="your_key_here" npx @deepseek-ai/dsh web
  5. 05

    Windows Command Prompt

    Use set in Command Prompt, then start DSH in that same window.

    set GATEWAY_API_KEY=your_key_here npx @deepseek-ai/dsh web
  6. 06

    macOS or Linux

    Export the variable in the same shell that will start DSH.

    export GATEWAY_API_KEY="your_key_here" npx @deepseek-ai/dsh web
  7. 07

    Select the model again

    Return to the input area, select a model under the provider you just configured and retry. If the old session still holds the previous provider or model, create a new session.

Verify MISSING_CREDENTIAL is fixed

  • Settings shows the provider as configured without revealing the full key.
  • The input area shows a specific provider and model instead of Select model.
  • A small text-only prompt completes without MISSING_CREDENTIAL.
What to avoid
  • Do not paste the real API key into Model ID or apiKeyEnv.
  • Do not publish the key in screenshots, logs or GitHub Discussions.
  • Do not change port, workspace or plugin settings for a credential-only error.
