Unable to parse CloudFormation JSON file

SonarQube

Hello,

Sonar scanner returns problem with parsing CloudFormation JSON file when there is any empty line.
It should be considered as a bug because breakline is valid JSON character.

Example:

{
  "AWSTemplateFormatVersion": "2010-09-09",
  
  "Resources": {
    "Topic": {
      "Type": "AWS::SNS::Topic"
    }
  }
}

Output:

|29-Jul-2022 10:39:35|ERROR: Unable to parse file: file:///MY_PATH/MY_FILE.json. Parse error at position 4:0|
|---|---|
|29-Jul-2022 10:39:35|ERROR: Cannot parse 'PATH/MY_FILE.json': while parsing a flow mapping|
|29-Jul-2022 10:39:35|in reader, line 1, column 1:|
|29-Jul-2022 10:39:35|    {|
|29-Jul-2022 10:39:35|    ^|
|29-Jul-2022 10:39:35|expected ',' or '}', but got ?|
|29-Jul-2022 10:39:35|in reader, line 4, column 3:|
|29-Jul-2022 10:39:35|      Resources: {|
29-Jul-2022 10:39:35	      ^

Hello @tabramczyk,

Welcome to the community. Please excuse the late reply to your report.
Indeed, we should not fail on empty lines in JSON files. To address this problem, I’ve created a ticket.

Best,
Nils
