Cannot set a RobotFramework dictionary - robotframework

Question

I wrote this simple minimal script to show how I suffer:
main.robot
Library Collections
Library BuiltIn
Library String
*** Variables ***
&{info} Create Dictionary
*** Test Cases ***
Case_00_Initialization
Log Hello 1 WARN
Set To Dictionary ${info} field1=A sample string
Log Hello 2 WARN
Running this code by
python -m robot -L TRACE --NoStatusRC main.robot
Gives me errors:
[ ERROR ] Error in file 'C:\test\main.robot' on line 7: Setting variable '&{info}' failed: Invalid dictionary variable item 'Create Dictionary'. Items must use 'name=value' syntax or be dictionary variables themselves.

The application is supposed to set a variable info in the initialization and it will be used in the next test cases. I do not want to use Set Global Variable however.
Please note that this is a minimal working example, do not suggest to set field1 at Variables section. It is not possible. Even that one will not solve the problem of No keyword with name 'Set To Dictionary' found.

Answer 1

In the Variables section you cannot use keywords - and this is exactly what you did with the Create Dictionary there.
You can add some key:values to it (like "field" , but you don't allow us that ;), or - you can initialize it to be an empty dictionary (e.g. like {} in python). The later is done by passing the special value &{Empty}:
*** Variables ***
&{info} &{Empty}

Answer 2

I eventually found what is wrong. I was missing the line for *** Settings *** I couldn't imagine that it does matter. Shame that RF does not have many full examples online.
This is the working code:
*** Settings ***
Library Collections
*** Variables ***
&{info}
*** Test Cases ***
Case_00_Initialization
Log Hello 1 WARN
Set To Dictionary ${info} field1=A sample string
Log Hello 2 WARN
