Generate Document node creating 0-byte files after SysFile entity modification

Hi Community,

I am experiencing an issue with a business process in Creatio where the Generate Document (Generate Report) node is not generating the document correctly.

The process executes without throwing a visible error, however:

• No document file is generated as expected (0 bytes),

As a result, any subsequent logic that tries to read the generated file fails, since the document content does not exist.

Additionally, we have a node in the process that modifies the SysFile entity. This implementation is necessary for document control purposes. Until last week, this configuration was not affecting the process; however, we have noticed that it is now preventing the file from being generated in the Attachments section.

Has anyone experienced a similar issue or knows what might be causing this behavior and how it can be resolved?

Thank you in advance for your support.
