[Health-dev] error export data products

[Edgar_H]

Dear all,

I use Oracle Virtual machine with openSUSE Leap 15.3 and GNUHealth 3.8. with demo-database

When I make a an export and then again a new export an error occurs:

File "/usr/lib/python3.6/site-packages/tryton/gui/window/form.py", line 334, in sig_export

context=self.screen.context)

File "/usr/lib/python3.6/site-packages/tryton/gui/window/win_export.py", line 30, in __init__

super(WinExport, self).__init__()

File "/usr/lib/python3.6/site-packages/tryton/gui/window/win_csv.py", line 102, in __init__

self.add_buttons(vbox_buttons)

File "/usr/lib/python3.6/site-packages/tryton/gui/window/win_export.py", line 76, in add_buttons

self.fill_predefwin()

File "/usr/lib/python3.6/site-packages/tryton/gui/window/win_export.py", line 178, in fill_predefwin

[f['name'] for f in export['export_fields.']],

KeyError: 'export_fields.'

Screenshots are available for the next two weeks at https://hagenbichler.at/error_export.pdf

Am I doing something wrong?

Thank you very much,

all the best
