I have JSON source where one of the fields has an escape character in the field name. Well actually I cannot see that in highlighted mode or in the extracted field list, it appears as "ReportRefreshDate", just in raw view: "\ufeffReportRefreshDate".
Naturally, the searches are not working with what appears as the "ReportRefreshDate". If I select the field it appears as " 'red dot' ReportRefreshDate", the search work, but can not be saved - it's "forget" the red dot, as any copy/ paste attempt does out of the search bar.
How can I rid of this? By adding
FIELDALIAS-alias1 = "\ufeffReportRefreshDate" AS "Report_Refresh_Date"
