Summary20032: PHP Error When Importing Participants From CSV
Description

Just realized this is only with debug>0, so very low priority.

When importing participants via CSV, if any rows are lacking a token (e.g. you're importing a bunch of emails and are going to use the "Generate access codes" feature to give them tokens) you will get a PHP error and the import will fail.

php error (see attachments for full stack trace):
preg_replace(): Passing null to parameter #3 ($subject) of type array|string is deprecated
/srv/www/limesurvey6/application/models/Token.php(315)

affected php versions:
7.4 - DID NOT TEST
8.0 - OKAY
8.1 - ERROR
8.2 - ERROR
8.3 - ERROR
8.4 - DID NOT TEST

NOTE: Mantis "Product Version" does not include 6.10.x

Steps To Reproduce

Steps to reproduce

  1. Create a survey
  2. Switch to closed access mode
  3. Import participants from CSV (you can use attached csv for testing)

Expected result

Participants are imported

Actual result

PHP error, participants are not imported
