Increase the maximum buffer size from 100

 Http request failed as there is an error: 'Cannot write more bytes to the buffer than the configured maximum buffer size: 104857600.'.


Please increase the maximum buffer size from 100 MB to something more real world.


Thank you

currently we are using Flow to upload files from Sharepoint to FTP. We would highly welcome a higher buffer size of 200 MB or a convenient way to handle bigger files from Sharepoint and to be able to upload these to FTP with Flow.


Any ideas on how to upload a PDF ( < 160MB) to an FTP Server with Flow are appreciated.

Yep agreed, especially annoying as there seems to be a disconnect between what a Form will allow (1Gb) and the Flow (104mb)
