Describe the bug
When mapping any operation that has no actual body and one of the method argumets is of type string[]? or StringValues according to the documentation the api should infer that to be from query string unless explicitly configured otherwise.
Although this actually works fine for calling the endpoint, when generating documentation an empty body appears.
This happens by simply using the WithOpenApi extension method. When I debug I find that the operation.RequestBody parameter is populated (should be null if you check with other operations).
The operation
// Bind to a string array.
// GET /tags2?names=john&names=jack&names=jane
app.MapGet("/tags2", (string[] names) =>
$"tag1: {names[0]} , tag2: {names[1]}, tag3: {names[2]}").WithOpenApi();The generated swagger json
{
"openapi": "3.0.1",
"info": {
"title": "WebApplication1",
"version": "1.0"
},
"paths": {
"/tags2": {
"get": {
"tags": [
"WebApplication1"
],
"parameters": [
{
"name": "names",
"in": "query",
"required": true,
"style": "form",
"schema": {
"type": "array",
"items": {
"type": "string"
}
}
}
],
"requestBody": {
"content": {
"application/json": { }
},
"required": true
},
"responses": {
"200": {

"content": {
"text/plain": {
"schema": {
"type": "string"
}
}
}
}
}
}
}
},
"components": { }
}Expected Behavior
There should not be a requestBody at all there.

}Steps To Reproduce
I have prepared a project here https://github.com/cleftheris/WithOpenApiBug
It is just the default aspnet 7 template with the below code added to the Project.cs
// Bind to a string array.
// GET /tags2?names=john&names=jack&names=jane
app.MapGet("/tags2", (string[] names) =>
$"tag1: {names[0]} , tag2: {names[1]}, tag3: {names[2]}").WithOpenApi();Exceptions (if any)
No response
