I am using Grails 3.2.0 with grails-spring-websocket 2.3.0.

Have you any idea/suggestion about that?

Thanks, Mario

could #41 be related? i.e. is your custom webSocketConfig bean defined in resources.groovy and subject to ComponentScan at the same time?

if so, one possible solution would be to exclude it from component-scanning and to keep it in resources.groovy (as that is needed to properly override the default webSocketConfig bean provided by the plugin).

how you do that depends on how you defined/activated your component scan.

as an example, if you defined it via the @ComponentScan annotation, you could add an exclude filter:

@ComponentScan(
    basePackages = "my.base.package",
    excludeFilters = @ComponentScan.Filter(type = FilterType.ASSIGNABLE_TYPE, value = MyCustomWebSocketConfig)
)
