TS1011: An element access expression should take an argument

[igor-spirin-indriver]

Description

After upgrading from v2.9.2 to v2.10.1 my project broke due to TypeScript error so I had to roll back.

TS1011: An element access expression should take an argument

To Reproduce

Here the test app code to reproduce:

package main

type Foo struct {
	Total int64            `json:"total"`
	List  map[string][]Bar `json:"list,omitempty"`
}

type Bar struct {
	Name string `json:"name"`
}

func (a *App) Issue() *Foo {
	return nil
}

func (a *App) GetLostModelsForVersion2_9_2() *Bar {
	return nil
}

The problem is in map[string][]Bar

Expected behaviour

Succesful build

I've fixed this locally by changing the renderer to use the Array<type> primitive instead of the postfix []. Happened to me as well under same scenario, it's working now. Looks to be a slight regression from this work: #3978

If you want to assign this to me I can take the ticket
