Trying to send email but Cannot read property 'label' of undefined

Hello,
I’m trying to send a “sales invoice” and i get in the console:

multiselect.js:38 Uncaught TypeError: Cannot read property 'label' of undefined
    at o.get_value (multiselect.js:38)
    at o.get_value (class.js:53)
    at o.get_values (multiselect.js:61)
    at o.get_data (multiselect.js:75)
    at o.get_data (class.js:53)
    at o.get_awesomplete_settings (autocomplete.js:29)
    at o.get_awesomplete_settings (multiselect.js:5)
    at o.get_awesomplete_settings (class.js:53)
    at o.setup_awesomplete (autocomplete.js:70)
    at o.make_input (autocomplete.js:6)

I tried to send other doctypes and i always get the same message

Thanks for your help
