I have mailchimp synchronization problems in reports and contacts and when downloading the error log I get this (attached images), could someone guide me on what to do please?

Hello.
What EspoCRM version and MailChimp version do you use?

[sandra6012]

EspoCRM 5.6.4
MailChimp 1.0.1

I can see you have a debug mode for logger set in your config file. You can change it to WARNING.

I have tested is and the MailChimp contact sync works as it should. Could you provide the EspoCRM error log file with the MailChimp sync error description?
