Error message

You have enabled logging out the prompt content with the risk of exposing sensitive or private information. Please, be careful!

What it means

ChatObservationAutoConfiguration.logPromptContentWarning emits this warning when chat model observation logging of prompt content is enabled. Prompt text may contain sensitive user data, so the library warns whenever the property opts you into logging it in observations.

Solutions

Set spring.ai.chat.observation.log-prompt-content=false in production.
Scope the property to dev/test profiles only.
If tracing needs content, use a telemetry backend with redaction and restricted access.

Example fix

// before (application.yml)
spring.ai.chat.observation.log-prompt-content: true
// after
spring.ai.chat.observation.log-prompt-content: false

Defensive patterns

Strategy: validation

Validate before calling

boolean loggingPrompts = env.getProperty(
    "spring.ai.chat.observation.log-prompt-content", Boolean.class, false);
if (loggingPrompts && isProduction) {
    throw new IllegalStateException("Prompt content observation logging must be off in production");
}

Prevention

Default log-prompt-content to false in shared config.
Gate content logging behind dev/test profiles.
Use a redacting telemetry processor if content tracing is mandatory.

When it happens

Trigger: Setting spring.ai.chat.observation.log-prompt-content=true (via ChatObservationProperties) so the conditional logPromptContentWarning bean method runs during auto-configuration.

Common situations: Turning on observation content logging for tracing in dev and promoting the config to production; compliance requirements (GDPR/PII) violated by prompt traces in log backends; copying sample tracing configs.
