Explictly we are only using the health and info actuator endpoints. See the below config for relevant configuration:
management.endpoints.access.default=none
management.endpoint.info.access=read_only
management.endpoint.health.access=read_only
management.endpoints.web.exposure.include=health,info
management.endpoints.web.base-path=/
management.endpoints.web.path-mapping.health=health
management.endpoint.health.probes.enabled=true
management.health.livenessState.enabled=true
management.health.readinessState.enabled=true
management.endpoint.health.show-details=always
management.info.env.enabled=true
However since updating to Spring Boot 3.4.0 and using the new endpoint Access syntax, when attempting to run in our deployed environment we have found the following startup issue.

This appears to be associated with the default being:
`management.auditevents.enabled=true`
We don't necessarily have a need for auditevents, though it seems to be a bug as it's trying to use the Access.java value of `none` and expecting a boolean
**Comment From: wilkinsona**
I don't think this is related to `management.auditevents.enabled`. The failure's occurring on line 65 of `PropertiesEndpointAccessResolver`:
https://github.com/spring-projects/spring-boot/blob/91778e9f96fa0ab561b43705c67a7236c4cbafe9/spring-boot-project/spring-boot-actuator-autoconfigure/src/main/java/org/springframework/boot/actuate/autoconfigure/endpoint/PropertiesEndpointAccessResolver.java#L65
This is reading the value of the `management.endpoints.enabled-by-default`.
Given the above, it would appear that `management.endpoints.enabled-by-default` has been set to `none` somewhere in your app's environment. It appears to be related to `AuditEventsEndpointAutoConfiguration` purely because that's the first auto-configuration that uses `@ConditionalOnAvailableEndpoint` to be processed. If you exclude that auto-configuration it'll then fail when processing `org.springframework.boot.actuate.autoconfigure.beans.BeansEndpointAutoConfiguration`.
Please check your application's environment and correct the value of `management.endpoints.enabled-by-default` to be `true` or `false`.
**Comment From: bashout**
We have removed all references to `management.endpoints.enabled-by-default` as it has been marked as deprecated, isn't this intended?
I do agree with the snippet provided and quintuple checking our configurations now. However since I've removed all references to it in our application files, I wouldn't expect it to be being configured.
**Comment From: wilkinsona**
The property isn't set by default so I believe you must have missed an occurrence where it's being set to a non-boolean value. It could be coming from a system property or an environment variable, for example, not just from application configuration files. If you debug your application with a breakpoint on line 65 of `PropertiesEndpointAccessResolver`, you should be able to step through the resolution process to find which property source it's coming from.
**Comment From: bashout**
Happy to say you put us on the right path. Turns out our env vars had conflicting names with the underlying spring properties, thus were overruling. Naivety on my part. Appreciate the direction!
**Comment From: wilkinsona**
Good to hear that you figured it out. Thanks for letting us know.
Boot could be more helpful here by handling the `ConversionFailedException` and throwing an `InvalidConfigurationPropertyValueException`. That would turn the lengthy stack trace above that doesn't tell you about the origin of the property value into something like this instead:
APPLICATION FAILED TO START
Description:
Invalid value 'none' for configuration property 'management.endpoints.enabled-by-default' (originating from 'System Environment Property "MANAGEMENT_ENDPOINTS_ENABLED_BY_DEFAULT"'). Validation failed for the following reason:
Failed to convert from type [java.lang.String] to type [java.lang.Boolean] for value [none]
Action:
Review the value of the property with the provided reason. ```
I've opened https://github.com/spring-projects/spring-boot/issues/43378 to track this.
