In my project I got an error while processing one of the files:
I investigated the problem and got to the line with if statement where the
exp.type
expression is compared to the string literal 'ExpressionStatement'. In some cases variableexp
is undefined. I added a simple check for variable existence (truthiness) as an additional condition to the if statement.A similar comparison with 'AssignmentExpression' literal is done originally in another fragment of code but in that case, proper check for variable existence (truthiness) is present.
