The same issue i am facing since this morning. I need to resolve this issue as soon as possible . can you help me out with this issue.

@jonhammer i resolved this issue . I think this step will resolve your issue also

In the commentjson.py file remove start = 'start'

parser = Lark('''
?start: value
?value: object
| array
| string
| SIGNED_NUMBER -> number
| "true" -> true
| "false" -> false
| "null" -> null
array : "[" [value ("," value)] "]"
object : "{" [pair ("," pair)] "}"
pair : string ":" value
string : ESCAPED_STRING

COMMENT: /(#|\/\/)[^\\n]*/

%import common.ESCAPED_STRING
%import common.SIGNED_NUMBER
%import common.WS
%ignore WS
%ignore COMMENT

''' ,start = 'start')

Confirm this. lark-parser==0.7.2 broke this. Wasn't a problem with 0.7.1

Just made a release to fix this issue. Solution suggested by @Sreevalli961 helped. Thanks for that. :)
