file_properties_properties_add() - InternalServerError('', 500, '')

Hello, 

Thank you very much for the answer.

I didn't one PropiertyGroup with more than one field because in that case this error raises:

Exception has occurred: ValidationError - PropertyGroup(template_id='ptid:iMdPSELQckAAAAAAAAAAIQ', fields=[PropertyField(name='date', value='1548965874'), PropertyField(name='park', value='x'), PropertyField(name='attraction', value='y'), PropertyField(name='file_type', value='video'), PropertyField(name='uid', value='AS46561sdg99wrDSD9e6f1e')]) is not a valid list.

Due to this, I was passing a list of PropertyGroup, one for each field I need to write and I get the 500 error,  so I'm stuck here.

This is what I do to create everything in case there is something wrong here:

self.dbx_api = dropbox.Dropbox(self.token, timeout=p_timeout)

# Confirm the access token is valid:
try:
    self.dbx_api.users_get_current_account()
except dropbox.exceptions.AuthError:
    sys.exit("ERROR: Invalid access token; try re-generating an access token from the app console on the web or asking to you System Administrator")

string_t = dropbox.file_properties.PropertyType.string
date = dropbox.file_properties.PropertyFieldTemplate(
                'date', 
                'Date when the file was upload', 
                string_t)
park = dropbox.file_properties.PropertyFieldTemplate(
                'park', 
                'Park where the media was done', 
                string_t)
attraction = dropbox.file_properties.PropertyFieldTemplate(
                'attraction', 
                'Attraction where the media was done', 
                string_t)
f_type = dropbox.file_properties.PropertyFieldTemplate(
                'file_type', 
                'Type of file (video/photo)', 
                string_t)
uid = dropbox.file_properties.PropertyFieldTemplate(
                'uid', 
                'Uniq identifier for the object', 
                string_t)

template = self.dbx_api.file_properties_templates_add_for_user(
                'media_file', 
                'Properties for media files (photos/videos)', 
                [date, park, attraction, f_type, uid])

self.template_id = template.template_id

date_property       = dropbox.file_properties.PropertyField('date', p_date)
park_property       = dropbox.file_properties.PropertyField('park', p_park)
attraction_property = dropbox.file_properties.PropertyField('attraction', p_attraction)
f_type_property     = dropbox.file_properties.PropertyField('file_type', p_f_type)
uid_property        = dropbox.file_properties.PropertyField('uid', p_uid)

property_group = dropbox.file_properties.PropertyGroup(
            self.template_id, [date_property, park_property, attraction_property, f_type_property, uid_property])

try:
     self.dbx_api.file_properties_properties_add(p_target_file, property_group)
except dropbox.exceptions.ApiError as err:
     sys.exit("ERROR: Add properties fail for " + p_target_file + " -- Property group alredy exist" + err)

In this case I get the error above, and if I try what I explain you the last day:

property_data = dropbox.file_properties.PropertyGroup(self.template_id, [date_property])
property_park = dropbox.file_properties.PropertyGroup(self.template_id, [park_property])
property_attrac = dropbox.file_properties.PropertyGroup(self.template_id, [attraction_property])
property_type = dropbox.file_properties.PropertyGroup(self.template_id, [f_type_property])
property_uid = dropbox.file_properties.PropertyGroup(self.template_id, [uid_property])

peropety_gr_list = [property_data, property_park, property_attrac, property_type, property_uid]

try:
     self.dbx_api.file_properties_properties_add(p_target_file, peropety_gr_list)
except dropbox.exceptions.ApiError as err:
     sys.exit("ERROR: Add properties fail for " + p_target_file + " -- Property group alredy exist" + err)

I got the 500 error. Also, I'd like to say that I already delete every Template in the user to work only with one first of all, but still in the same situation.
