This error indicates that the summary field isn't present on the create screen for the project. This is unusual, you should review the screen for the for the project and add the summary field.

If the summary field is present then you should check the api format against Atlassian's documentation here: https://developer.atlassian.com/cloud/jira/platform/rest/v3/api-group-issues/#api-rest-api-3-issue-post

It's possible that the format isn't exactly correct which could be causing Jira to look for a second summary field.
