ICS: Error reading file with ftp adapter

Content

Hello, I am trying to read an ERP report previously stored in the FTP.
The steps followed on the next.

1)- Write the report in base64 in the FTP directory using ftp adapter without template.

2)- Read the report from the FTP using the connector with a template

This solution helps me when the report is small, when it does not exceed 1MB in size but having more I have the following error:

Translation Error. Translation Error. Error while translating message to native format. Please make sure that the payload for the outbound interaction conforms to the schema.

I do not see that the report brings something strange.
