We've been monitoring the errors Pipedrive were returning today, and we've not seen an error returned in the past 60 minutes. With that in mind we're marking this issue as resolved.
If you have some Tasks in your Task History showing the error, you should now be able to Replay them succesfully. If you need some help with that, please check out our support article here: https://zapier.com/help/task-history/#how-do-i-replay-a-task-that-was-not-successful-or-had-an-error
If you'd like some further support, please contact us (https://zapier.com/app/contact-us
