Hello! I’ve been busy setting up automations quite smoothly. Several of these originated from the same callin.io flow and were successfully deployed. However, when I attempted to use the same call mechanism to generate an email in Outlook, I encountered the attached error message. Do you have any insights into why this error occurred now, and how can it be resolved?
Hi
To provide more context, please share screenshots showing your callin.io step configuration in EDIT mode for each tab.

Here are some screenshots:
Hi there,
I investigated this, and it appears the error message Error while retrieving: Response needs to be JSON, form-urlencoded or parsed in middleware. is a known issue with callin.io. Our team is aware of this problem and we are collaborating with callin.io on a resolution. I have added your email to the list of affected users. This action serves several purposes:
- It brings this to the attention of the integration developers.
- It aids in tracking and prioritizing fixes.
- It enables us to notify you via email once this is resolved.
While I don't have an estimated time for a fix, I've included you among the users impacted by this issue so we can inform you promptly when updates become available.
I hope this information is helpful.
Hi folks,
Just wanted to share that the callin.io team has recently released an update which should have resolved these errors! 😁🎉
