Request Entity Too Large when transferring data between FormStack and Excel

We have a simple automated flow as seen below, where, once a form document is submitted in FormStack, that information gets written into and excel table.

Users that submit the form can also append a .pdf document to it, so we have a few uriComponentToBinary operations that convert the document for future use. We run into an issue where some submitted documents are considered too large (a particular one was 14 Mb) which results in the following error:

            }
        }
    }
}

 

Is this issue fixable, or is there a limit for such operations in PowerAutomate?

Thank you!
