Contact Import Error: VCard object with uid already exists in this addressbook collection.

[schast]

Describe the bug

Error on importing already existing vcards.

Steps to reproduce

1. Go to contacts -> contact settings
2. Click on contact import
3. Upload File (Toni_Testeroni.vcf):

BEGIN:VCARD
VERSION:3.0
N:Testeroni;Toni;;;
FN:Toni Testeroni
TEL;TYPE=home,voice:+43 123 456789
TEL;TYPE=cell,voice:+43 664 123456789
ADR;TYPE=home:;;Straße 123-456;Ort;;1234;Land
URL;TYPE=home:http://toni.testeroni.com
X-SOCIALPROFILE;TYPE=FACEBOOK:FacebookUser
X-SOCIALPROFILE;TYPE=SKYPE:SkypeUser
X-SOCIALPROFILE;TYPE=LINKEDIN:LinkedInUser
X-SOCIALPROFILE;TYPE=INSTAGRAM:InstagramUser
X-SOCIALPROFILE;TYPE=MASTODON:MastodonUser
BDAY:1990-01-01

UID:urn:uuid:9130b79c-9f59-456e-a96b-bf633fac5882
END:VCARD

4. The vcard is successfully imported the first time it is created.
5. Upload the card again (the error also occurs with the REV field updated to the current timestamp).
6. See error in Browser Debug Console (Networking Tab)

Same problem !
Since when does it appear for you?

STRANGE:

1. export a contact vcf file via web UI: afilenameofcontactexport.vcf
   If the file name in the url is the same of a contact export file, it works with this command:
2. with curl -X PUT -u "$user":"$pass" "https://${cloud}/remote.php/dav/addressbooks/users/$user/$addressbook/afilenameofcontactexport.vcf" -T "$xfile"
   You can change the content for any contact UID. It works. but with another name, it does not.
3. with curl -X PUT -u "$user":"$pass" "https://${cloud}/remote.php/dav/addressbooks/users/$user/$addressbook/" -T "$xfile" it sends the error "VCard object with uid already exists in this addressbook collection"

[LionelHoudelier]

SOLUTION :
extract the UID of file :
uid=$(grep UID "$xfile" | sed 's/.*://')
add it to the url + ".vcf"
then it works
PS: we have to have added first the new contacts with this procedure.

Here is a full script to add AND update contacts from one file with some vcard:

#!/bin/bash
#### ENTER YOUR DATAS ##########
# folder to parse the file
temp_folder=/home/.....
# folder where is the vcf file
folder='/home/...'
filename='VCARD_FILE.vcf'
user='XXX'
pass='XXXXX'
addressbook='XXXX'
cloud='your.nextcloud.url'
##########################################################
filepath="$folder""$filename"
url="https://${cloud}/remote.php/dav/addressbooks/users/$user/$addressbook"
echo $url
# parse the file in multiple random files name
mkdir -p $temp_folder
rm -f $temp_folder/*
echo "$folder"
inotifywait --format="%w%f" -m "$folder" -e moved_to |
    while read file; do
  if [[ "$file" == *".vcf" ]]
  then 
  awk -v temp_folder="$temp_folder" 'BEGIN {
        RS="END:VCARD";
        }
        {
        command = "echo -n '$temp_folder'/$(pwgen 20 1).vcf"
        command | getline filename
        close(command)
        print $0 "END:VCARD" > filename
        close(filename)
        }' "${filepath}"
      for xfile in "$temp_folder"/*.vcf; do
        if grep -q "BEGIN:" "$xfile"; then
          uid=$(grep UID "$xfile"  | sed 's/.*://')
          echo "UID : " "$uid"
          curl -X PUT -u "$user":"$pass" "$url/$uid.vcf" -T "$xfile"
          echo "ok"
          rm "$xfile"
        fi
      done
  fi
done
command = "echo -n '$temp_folder'/$(pwgen 20 1).vcf"
        command | getline filename
        close(command)
        print $0 "END:VCARD" > filename
        close(filename)
        }' "${filepath}"
# upload the files
      for xfile in "$temp_folder"/*.vcf; do
        if grep -q "BEGIN:" "$xfile"; then

          uid=$(grep UID "$xfile"  | sed 's/.*://')
          echo "UID : " "$uid"
          curl -X PUT -u "$user":"$pass" "$url/$uid.vcf" -T "$xfile"
          echo "ok"
          rm "$xfile"
        fi
      done
  fi
done
rm -f $temp_folder/*
