ApplicationService > ListenForCustomConfigChanges > Delete from map is not working

[EdoardoLenzi9]

🐞 Bug Report

Affected Services: ApplicationService

The issue is located in: ListenForCustomConfigChanges callback

Is this a regression?

No

Description and Minimal Reproduction

In an ApplicationService the ListenForCustomConfigChanges seems to have a bug on DELETE event.

Given a data structure of this form:

type Foo struct {
	Bar            string // any content
}

type Config struct {
	Foos map[string]Foo // map[string]Anystruct
}

When I delete from the Consul an item of Foos it is still present in the ListenForCustomConfigChanges callback (probably cached).

Therefore the state of the App is not consistent with the actual state (Consul state).

When I restart the service the map Foos is consistent with Consul again.

🔥 Exception or Error

None

@EdoardoLenzi9 We are releasing v4.0 soon and Consul will no longer be supported. Core Keep is the new default config provider in v4. Could you please confirm if this issue can be reproduced in the main branch with Core Keeper?
