VTL adds whitespaces to string

I am using mapping template in AWS API Gateway methods Integration response. I found that it adds unwanted whitespaces to the return string. I have read Velocity references and tried all trimming and replacing I could think of. However there still seems to be 3 whitespaces before text. My actual code is more complicated but this is a short example of the problem.

#set ($test = "Foo bar")
##return that
$test.toString().trim()

Most probably, the extra spaces come from elsewhere in the template.

First, you can try to add some extra characters to understand where the spaces come from:

<#set ($test = "Foo bar")>
@@##return that
<$test.toString().trim()>

and look where the spaces do fall.

Also, you can try to comment end lines to see if it changes something:

#set ($test = "Foo bar")##
##return that
$test.toString().trim()##
