Hello Davide,

Can you please share your Integration Flow steps and there configuration along with your ODATA Channel?

Also, can you enable Trace ( Header And Body ) for your Integration flow and see which step this fails in and the error accordsingly? You can refer to these blogs for Tracing & Logging -
