I've a function which return a pdf report return { 'type': 'ir.actions.report.xml', 'report_name':'hotel.product.label', 'datas': { 'model':'hotel.product', 'ids': pids and pids or [], 'report_type': 'pdf' }, 'nodestroy': True }

pids is list of ids with duplicate keys eg: pids = [1,1,1,2,2,2,2,2,3,3,3]

The function returns a report for only unique ids i.e. [1,2,3] only. I did debugging and saw that werkzeug serving.py line #130 assert type(data) is str, 'applications must write bytes' self.wfile.write(data) self.wfile.flush()

has all keys in data attribute which is last function called before returning the report. Please let me know if to provide more specifications for the issue. Any guidance or help would be highly appreciated.
