Field 'fixVersions' cannot be set. It is not on the appropriate screen, or unknown

[uaoleg]

This error is caused by setting a default value for $fixVersions = []
https://github.com/lesstif/php-jira-rest-client/blob/main/src/Issue/IssueField.php#L50

And because of that it's not filtered out by !is_null

Hello, I have version 5.10
In our system there is no fixVersions field and we get an error:
{"errorMessages":[],"errors":{"fixVersions":"Field 'fixVersions' cannot be set. It is not on the appropriate screen, or unknown."}}

Can you please add this code in jsonSerialize(), class IssueField

if (empty($this->fixVersions)) {
    unset($vars['fixVersions']);
}

@DreamyDevil that code already exists https://github.com/lesstif/php-jira-rest-client/blob/main/src/Issue/IssueField.php#L117
What we need is to replace !is_null with !empty

Created a PR #548

I think this error occurs in newer Jira versions.
In our case, we needed this fix, and also this change: #549 to make the integration work again.

We have the same problem, is there perhaps a fixed version on the horizon?
