Slice of array causes wails generate module to fail

[thetechpanda]

Description

wails generate module fails when a slice of array is part of an exported struct.

This bug could be related to #2323, #2303 too.

To Reproduce

1. wails init -n test-bug
2. cd test-bug
3. go get github.com/google/uuid
4. Add the following lines to app.go and add "github.com/google/uuid" to the imports

/* Copy the following code to your app.go file */
/* Add "github.com/google/uuid" to the imports */

type Works struct {
	Bytes   [1]byte   `json:"bytes" validate:""`
	Strings [1]string `json:"strings" validate:""`
	UUID    uuid.UUID `json:"uuid" validate:""`
}

type DoesNotWork struct {
	Bytes   [][1]byte   `json:"bytes" validate:""`
	Strings [][1]string `json:"strings" validate:""`
	UUIDs   []uuid.UUID `json:"uuids" validate:""`
}

// modules are generated
func (a *App) Works() Works {
	return Works{}
}

// modules are not generated
func (a *App) DoesNotWork() DoesNotWork {
	return DoesNotWork{}
}

5. go mod tidy
6. wails generate module

The following are obtained by having only one of DoesNotWork struct fields at the time.

DoesNotWork.Bytes

2024/04/28 14:15:04 Error: cannot find type for array (bytes/)

DoesNotWork.Strings

2024/04/28 14:15:46 Error: cannot find type for array (strings/)

DoesNotWork.UUIDs

2024/04/28 14:16:21 Error: cannot find type for array (uuids/UUID)

Expected behaviour

modules are generated
