Python query search_issues(query,fields="key", maxResults=False)

[Rofl Lmao]

Hello, 

I have had this python query for few years now that used to return me all the issues I needed, 
Python query  - search_issues(query,fields="key", maxResults=False)
I know that "key" is not inside fields but it always worked for me. Since a few days ago I get response as None and when removing the fields="key", the query does work as expected. Was there a recent change to it? Maybe it ignored invalid fields or something?

Note - im using API 2

Thanks a lot.

Hi, @Rofl Lmao 

This can happen due to changes in REST endpoints, used to search issues.
Atlassian deprecated search endpoints and announced it here:
https://developer.atlassian.com/cloud/jira/platform/rest/v3/api-group-issue-search/#api-rest-api-3-search-get

If you're using some python library to work with Jira - try to update it. 
If you wrote your own code, using requests, for example, make all necessary changes to use new, correct, endpoint to search for issues.
