The Set Variable keyword is used to assign a static (e.g. "predefined") value to a variable. In a programming language this line

${headers}=   Set Variable     Get SessionToken

would be equivalent to:

headers =  "Get SessionToken"

The variable ${headers} now has as a value the string "Get SessionToken", regardless there is a keyword with the same name (for the framework that's just a coincidence (in fact, the framework doesn't "care" or "know" for this coincidence)).

If you want to store the return value of the keyword Get SessionToken - then just assign it:

${headers}=     Get SessionToken

${headers} will now have as a value whatever the content of ${SessionToken} was.

You could be even more explicit with this construct:

${headers}=     Run Keyword    Get SessionToken

, but that's just bad style (Run Keyword has very solid usages, just not in simple/trivial constructs like this).

Bear in mind the headers parameter in the Get Request keyword expects a dictionary, so be sure what ends up there is of this type.
This was precisely the error you got - as you've assigned a string value to the argument, it failed with the exception it's not a dict. (technically, it raised the exception a string object doesn't have the items() method - e.g. the keyword presumes the type and tries to use it as a dict)
