Error Message

Error: Config validation failed: <root>: Unrecognized key: "OPENAI_API_KEY"

Fix Action

Fix / Workaround

Method 1: Using gateway config.patch

I tried patching the configuration with the API key directly:

openclaw gateway config.patch --raw '{ "plugins": { "entries": { "openai": { "config": { "apiKey": "sk-..." } } } } }'

This resulted in the following error:

invalid config: plugins.entries.openai.config: invalid config: must NOT have additional properties

Code Example

openclaw gateway config.patch --raw '{ "plugins": { "entries": { "openai": { "config": { "apiKey": "sk-..." } } } } }'

---

invalid config: plugins.entries.openai.config: invalid config: must NOT have additional properties

---

openclaw config set OPENAI_API_KEY "sk-..."

---

Error: Config validation failed: <root>: Unrecognized key: "OPENAI_API_KEY"

---

openclaw config set plugins.entries.openai.config.apiKey "sk-..."

Hello,

I'm trying to configure the OpenAI provider for TTS but I'm running into persistent configuration errors. My OpenClaw version is 2026.4.15 (commit 041266a).

I've attempted several methods to set the API key, all of which have failed.

Method 1: Using gateway config.patch

I tried patching the configuration with the API key directly:

openclaw gateway config.patch --raw '{ "plugins": { "entries": { "openai": { "config": { "apiKey": "sk-..." } } } } }'

This resulted in the following error:

invalid config: plugins.entries.openai.config: invalid config: must NOT have additional properties

Method 2: Using openclaw config set

Based on documentation, I tried using the config set command.

First attempt (top-level key):

openclaw config set OPENAI_API_KEY "sk-..."

Error:

Error: Config validation failed: <root>: Unrecognized key: "OPENAI_API_KEY"

Second attempt (full path):

openclaw config set plugins.entries.openai.config.apiKey "sk-..."

Error:

Error: Config validation failed: plugins.entries.openai.config: invalid config: must NOT have additional properties

Method 3: Using gateway config.apply

I read the entire configuration, manually added the openai plugin entry with the apiKey, and tried to apply the full configuration file. This also resulted in the must NOT have additional properties error.

The tts tool confirms that the OpenAI provider is not configured.

It seems the configuration schema is preventing any additions to the plugins.entries.openai.config object via the available CLI tools. Could you please advise on the correct procedure to set the OpenAI API key for TTS in this version? Is there a different command or a required structure I'm missing?

Thank you.

extent analysis

TL;DR

The issue is likely due to the configuration schema restrictions, and a potential workaround is to explore alternative configuration methods or verify the expected structure for the openai plugin configuration.

Guidance

  • Review the OpenClaw documentation for the openai plugin to ensure the correct configuration structure is being used, as the error messages suggest the presence of additional properties not allowed by the schema.
  • Verify if there are any specific environment variables or configuration files that need to be updated for the OpenAI API key, as the config set commands did not yield the expected results.
  • Consider reaching out to the OpenClaw community or support channels for version 2026.4.15 (commit 041266a) to confirm the correct procedure for configuring the OpenAI provider, as the standard methods have been exhausted.
  • Check if there are any open issues or pull requests related to configuration schema restrictions or OpenAI plugin integration in the OpenClaw repository.

Example

No code example is provided due to the lack of a clear, working configuration method in the issue description.

Notes

The provided error messages and configuration attempts suggest a schema validation issue, but without further information on the expected configuration structure for the openai plugin, it's challenging to provide a definitive solution.

Recommendation

Apply workaround: Given the constraints and errors encountered, exploring alternative configuration methods or seeking community support is recommended to find a suitable workaround for setting the OpenAI API key in this version of OpenClaw.
