из-за того, что параметр пути `item_id` имеет значение `"foo"`, которое не является типом  `int`.

## Response with arbitrary `dict`

You can also declare a response using a plain arbitrary `dict`, declaring just the type of the keys and values, without using a Pydantic model.

This is useful if you don't know the valid field/attribute names (that would be needed for a Pydantic model) beforehand.

In this case, you can use `typing.Dict` (or just `dict` in Python 3.9 and above):

```Python hl_lines="6"

  echo The java installation you have is not up to date
  echo Activator requires at least version 1.6+, you have
  echo version $java_version

  echo Please go to http://www.java.com/getjava/ and download
  echo a valid Java Runtime and install before running Activator.
  echo
  exit 1

# if configuration files exist, prepend their contents to the java args so it can be processed by this runner

	// present, it is as good as object not found.

    "name": "Foo",
    "description": "An optional description",
    "price": 45.2,
    "tax": 3.5
}
```

...as `description` and `tax` are optional (with a default value of `None`), this JSON "`object`" would also be valid:

```JSON
{
    "name": "Foo",
    "price": 45.2
}
```

## Declare it as a parameter

To add it to your *path operation*, declare it the same way you declared path and query parameters:

	t.Run("Account", func(t *testing.T) {
		AssertObjEqual(t, user.Account, expect.Account, "ID", "CreatedAt", "UpdatedAt", "DeletedAt", "UserID", "Number")

		if user.Account.Number != "" {
			if !user.Account.UserID.Valid {
				t.Errorf("Account's foreign key should be saved")
			} else {
				var account Account
				db(unscoped).First(&account, "user_id = ?", user.ID)

	}
	defer os.RemoveAll(file)

	// Check if file is given.
	if _, err := readDir(path.Join(file, "mydir")); err != errFileNotFound {
		t.Fatalf("expected = %s, got: %s", errFileNotFound, err)
	}

	// Only valid for linux.
	if runtime.GOOS == "linux" {
		permDir := path.Join(os.TempDir(), "perm-dir")
		if err := os.MkdirAll(permDir, os.FileMode(0o200)); err != nil {
			t.Fatal(err)
		}
		defer os.RemoveAll(permDir)
