Creating a simple mail attachment to FTP flow. Having a new issue.
I have three of these running without issues on this account. Created a couple of weeks ago.
Im currently creating the same setup for a customer, with a newly created account. With the same configuration i get an error at my FTP Create File step.
I observed that this user has a couple of new features. Example new types of steps (Apply to each, do until, scope).
I don't have these on my other account. And the flow is automaticly converted to an Apply to each step for the attachments.
The flow creates this error for each attachment in the email
Screenshot of my create file step.
Appreciate any tips.

I'm having this same issue, only it's on existing flows that I've edited since Tuesday.
Have tried create OneDrive for Business, Sharepoint, and SFTP upload from an email attachment. All fail with this same error code.
Unable to process template language expressions in action 'Create_file' inputs at line '1' and column '11': 'The template language function 'base64ToBinary' expects its parameter to be a string. The provided value is of type 'Null'.
I created several simple flows to save attachment to OneDrive, Google Drive, SharePoint Online, Dropbox, FTP Server when a new email arrived. But all the flows were failed and the same error message occurred. Below is a screenshot of one of my flow “create file to Dropbox”.
For this issue, you could send a feedback by using the smile icon in Flow.
I run into the same issue. The following workaround works for me:
1. Create a new flow from the template (e.g. "save email attachment to sharepoint")
2. Modify the created flow according to your requirements.
