Invalid compressed file

[szakmaster]

We already use the log file generation with Serilog.Sinks.File in our .NET 6 project and want to add the compressed log file output to a separate folder archiving the logs. However, the created compressed files are corrupted, they are invalid.

Serilog is configured via appconfig.json:

"Serilog": {
"Using": [ "SeriLog.Sinks.Console", "Serilog.Sinks.File", "Serilog.Sinks.Async" ],
"MinimumLevel": {
"Default": "Information",
"Override": {
"Microsoft": "Warning",
"System": "Warning"
}
},
"WriteTo": [
{
"Name": "Console"
},
{
"Name": "File",
"Args": {
"path": "Logs/log.gz",
"rollingInterval": "Day",
"formatter": "Serilog.Formatting.Json.JsonFormatter, Serilog",
"hooks": "Serilog.Sinks.File.GZip.GZipHooks, Serilog.Sinks.File.GZip"
}
},
{
"Name": "File",
"Args": {
"path": "Logs/log.log",
"rollingInterval": "Day",
"formatter": "Serilog.Formatting.Json.JsonFormatter, Serilog"
}
}
],
"Enrich": [ "FromLogContext", "WithMachineName", "WithThreadId" ],
"Properties": {
"Application": "MyApplication"
}
}

Hmm, is the app being properly shutdown, with a call to Serilog.Flush() before termination?

My guess here is that the ZIP write stream is being terminated while it's still being written to.
