Serilog Eventid is logged as Json - serilog

Question

logger:
ILogger logger = new LoggerConfiguration()
.ReadFrom.Configuration(configuration, "Logging")
.Enrich.FromLogContext()
.CreateLogger();
settings:
"Logging": {
"Using": [ "Serilog.Exceptions", "Serilog", "Serilog.Sinks.File"],
"MinimumLevel": {
"Default": "Information",
"Override": {
"System": "Information",
"Microsoft": "Information",
"Microsoft.EntityFrameworkCore": "Information"
}
},
"WriteTo": [
{
"Name": "File",
"Args": {
"path": "./logs/events.log",
"rollingInterval": "Day",
"retainedFileCountLimit": 7,
"buffered": true,
"outputTemplate": "{Timestamp:u};{host_ip};{enviroment_hostname};{EventId};{EventCategory};{EventSeverity};{Message:lj};{UserId};{ResourceType};{ResourceId}",
"restrictedToMinimumLevel": "Information"
}
}
],
"Enrich": [ "WithExceptionDetails", "WithProcId", "WithFacility", "ProcessHostEnricher", "WithSeverity" ]
}
In the file I get the following output:
2023-01-13 15:43:25Z;;;{ Id: 101 };UserRolesUnAssigned;UserManagement;Medium;User:system roles un-assigned:role1,role2,role3;system;;
{EventId} comes out as a json object.
I would need just the Id. so 101 instead of { Id: 101 }
EDIT:
LoggerMessageDefinition:
private static Action<ILogger, string, string, Exception?> UserRolesUnAssigned =>
LoggerMessage.Define<string, string>(LogLevel.Information, 101, UserMessageCodes[101].Template);
public static void LogUserRolesUnAssigned(this ILogger logger, string userId, string roleNames)
{
EventDefinition eventDefinition = UserMessageCodes[101];
using (LogContext.PushProperty(EventConstants.EventName, eventDefinition.Name))
using (LogContext.PushProperty(EventConstants.EventCategory, eventDefinition.Category))
using (LogContext.PushProperty(EventConstants.EventSeverity, eventDefinition.Severity))
UserRolesUnAssigned(logger,userId, roleNames, null);
}
Is there a way to do this out of the box or do I need to create a custom enricher for this?
