Start by obtaining the exact fx command, JSON path, and shell context behind the reported “no such file or directory” message, then reproduce it on the stated Ubuntu environment. Compare opening an existing file with the confirmed stdin example; done means the file invocation works reliably and the original failure has a documented or tested explanation.
