JIRA API failed to create issue

[martinisgood]

We are trying to create some issues in a specific sprint using the Jira API. While most situation work fine, we encounter an error in some individual sprints. The error message is ‘400: [{‘errorMessages’: [‘Sprint does not exist.’], ‘errors’: {}}]’. we can make sure that all sprints are created by hand on the board,so there has any suggestion?

Additionally, the API we are using is "/rest/api/2/issue"

Furthermore, the sprints that cause errors are on different boards than the successful sprints.

It’s quite magical that creating an issue manually on the interface for these failed sprints, and then calling the API, results in success.
