IndexError: string index out of range when parsing a dashboard

[alvestobias]

I'm having this error when trying to parse a dashboard file. It works normally with explore and views tho. Any idea what it might be? Thanks!

load(stream)
     48 else:
     49     raise TypeError("Input stream must be a string or file object.")
---> 50 tree: DocumentNode = parse(text)
     51 visitor = DictVisitor()
     52 tree_as_dict: dict = visitor.visit(tree)  

 17 """Parse LookML into a parse tree.
     18 
     19 Args:
   (...)
     24 
     25 """
     26 lexer = Lexer(text)
---> 27 tokens = lexer.scan()
     28 parser = Parser(tokens)
     29 tree: DocumentNode = parser.parse()

Lexer.scan(self)
     90     self.advance()
     91     self.tokens.append(tokens.ValueToken(self.line_number))
---> 92     self.tokens.append(self.scan_expression_block())
     93 else:
     94     # TODO: This should actually check for valid literals first
     95     # and throw an error if it doesn't match
     96     self.tokens.append(self.scan_literal())

in Lexer.scan_expression_block(self)
    160 chars = ""
    161 while self.peek_multiple(2) != ";;":
--> 162     if self.peek() == "\n":
    163         self.line_number += 1
    164     chars += self.consume()

def peek(self) -> str:
     33     """Returns the character at the current index of the text being lexed."""
---> 34     return self.text[self.index]

IndexError: string index out of range

LookML dashboard files are defined in YAML and not LookML, so you should use a generic YAML parser like PyYAML for those!
