Hello there,
since some weeks we have some problems with our Custom Field.
const VoucherFieldEdit = () => {
const {extensionContext, platformContext} = useProductContext();
const {issueKey} = platformContext as JiraContext;
const {fieldValue} = extensionContext as CustomFieldExtensionContext;
const [, setVoucherId] = useIssueProperty<string>('voucher_id', '');
/*
.....
*/
}
When trying to create a new issue following error appears:
Error: product context does not contain issueKey for the useIssueProperty hook
at Object.exports.useIssuePropertyWithRequest (voucher-field.js:1485:15)

When trying to wrap useIssueProperty in a if(issueKey) following error appears (on edit):
Error: cannot use a hook outside of a component
