django-DefectDojo: Unable to import from Github vulnerability scan

Bug description When I am trying to import a Github vulnerability scan using the template given at [https://defectdojo.github.io/django-DefectDojo/integrations/import/#github-vulnerability]. I am receiving the error An exception error occurred during the report import:Expecting value: line 1 column 1 (char 0).

I did some digging on the internet and found that in some Ubuntu systems, python2.7 can’t identify json even if it’s a built-in function. Hence, I used the shebang #!/usr/local/bin python3 to prioritise python3. But I am still getting the error.

Steps to reproduce Steps to reproduce the behaviour:

1. Go to ‘Products’
2. Click on ‘Product name’
3. Click on ‘Findings’ dropdown
4. Click on ‘Import Scan Results’
5. Select scan type as ‘Github Vulnerability Scan’
6. Choose a report file to import

Expected behaviour Issues should populate in Finding. Because when I run the same python script locally on a terminal. It gives me expected results
