Hi @Yu, Fish （喻翔） ,
What is your project type?
Is it running in docker?

Yes, this project is designed to running in K8s, but I have removed all the settings related to docker. Just leave some items array which would cause this error.
You can replace the array with other object, this error still happens.
For example,
{
"profiles": {
"Host": {
"commandName": "Project",
"launchBrowser": true,
"environmentVariables": {
"ASPNETCORE_ENVIRONMENT": "Development",
"MESSAGING__RABBITMQ__HOSTNAME": "xxxxxxx",
"MESSAGING__RABBITMQ__CREDENTIAL__PASSWORD": "xxxxxxx"
},
"test": [
{"test1": "test1"},
{"test2": "test2"}
` ]
}
}
}

Hi @Yu, Fish （喻翔） ,
I did not reproduce the problem using the code you provided.
Have you tried creating a new project to see if the problem still happens?

But I can reproduce in my local. Any idea? Maybe the version?

This is the dotnet core sdk that this project used

Hi @Yu, Fish （喻翔） ,
I use version 3.1.2 of asp.net core SDK and version 17.4.1 of VS2022.
Maybe you can try updating your VS2022.

Best Regards.
