I had one of my field 'published_date' as 'timestamp' datatype.But eventually I had to make it as 'string' . I corrected in my schema file. But both db and elastic search suggested that it must be timestamp while adding new record.
I solved in db by deleting previous table from db......and new table was created by server with corrected schema.
But I dont know how to solve in elasticSearch.It still says that 'published_date' must be 'timestamp' datatype.(I know its data is stored in data folder inside nxsever, but i dont know how to delete its previous schema)
