Error on scheduled job, 'mail reports'
Notice: Undefined index: message in /var/www/sln/wordpress/wp-content/plugins/civicrm/civicrm/CRM/Core/JobManager.php on line 285
The error comes from the "mail reports" daily job:
Parameters raw (from db settings):
instanceId=[ID of report instance] required format=[csv or print] optional-output CSV or print-friendly HTML, else PDF Parameters parsed (and passed to API method): a:3:{s:7:"version";i:3;s:10:"instanceId";s:32:"[ID of report instance] required";s:6:"format";s:67:"[csv or print] optional-output CSV or print-friendly HTML, else PDF";}
Full message:
Finished execution of Mail Reports with result: Failure, Error message: is not of type String
WordPress 5.4.2, PHP 7.3, Civi 5.27.0
Report 32 is "mail opened". When I run this manually, I get an error
Warning: Declaration of CRM_Mailchimp_Permission::check(permissions) should be compatible with CRM_Core_Permission::check(
permissions, $contactId = NULL) in /var/www/sln/wordpress/wp-content/uploads/civicrm/ext/uk.co.vedaconsulting.mailchimp/CRM/Mailchimp/Permission.php on line 40
And now I'm at a loss for what to do next.
