getDuplicateContacts PHP Deprecation Notice when scheduled job runs

[justinmosier]

Issue

When the scheduled job runs to create Drupal CMS users for CiviCRM contacts assigned to a tag "missing cms user", the job triggers an admin email notification with this message repeated once per cms user created:

Cron job output:

[PHP User Deprecation] passing in mis-formatted date values is deprecated Caller: CRM_Contact_BAO_Contact::getDuplicateContacts at /home/mysite/www/mysite/vendor/civicrm/civicrm-core/CRM/Core/Error.php:1161

The job does what it's supposed to: it successfully creates the cms users for the tagged contacts, but it's throwing these noisy errors.

What it should do

Complete the job without throwing errors

Environment

• Dev & Production sites running CiviCRM 6.9.1 + Drupal 10.6.1
• PHP 8.3

• Are you passing any date fields (for example, birth date)?

• Please refer to this change for context:
  https://github.com/civicrm/civicrm-core/pull/31934/changes

• Is it possible to share more details on this?

• Specifically, I’d like to understand:

  • The values present in $fields
  • In the method formatParams()
  • Located at:
    /home/mysite/www/mysite/vendor/civicrm/civicrm-core/CRM/Dedupe/Finder.php

@sunilpawar

• No date fields are passing in (at least not to my knowledge).

On the CMS User Setting screen (/civicrm/admin/cmsuser), I've got these settings:

• Username pattern: {contact.email_primary.email}
• Sync preferred language: checked
• Assign Role to Users:
• Create CMS User for Tagged contact: the tag named "missing cms user"

That's it. The "Drupal User Fields" is blank. I'm not passing in any date tokens, like birth date or deceased date. But the CiviCRM contacts for whom I'm creating the Drupal CMS users do have non-empty birth date fields. Not sure if that would matter.

Separately I'll look into Finder.php and see if I can dig up further details.

[justinmosier]

ok it turns out the core date field birth_date was triggering the warning because it's formatted as a string [birth_date] => 1969-07-20 instead of the YmdHis format (e.g., "19690720000000") that formatParams expects.

Here's the $fields data passed into CRM_Dedupe_Finder::formatParams($fields, $ctype):

@sunilpawar I just created a PR that tested ok on a dev server.
