Impossible to import issues in a JSON file from Github API

[Marion Carré]

I exported issues from a Github repository as a JSON file to import them on Jira with the JSON import assistant but

first I had the following error : 

"There was a problem validating the json file. The fields [] are not valid." 

Then I removed the [] at the beginning and the end of the file, the import worked successfully but nothing was imported :

Can you help me ?

We had a similar issue.

We had to create an JSON object to feed it to the importer... It just didn't work with simple json data.

We fixed it by :

List<Users> list = getUsers();
String inputUserList = new ObjectMapper().writerWithDefaultPrettyPrinter().writeValueAsString(list);

Thanks ! Do you think this could also work to import issues and not users ?
