Hi @ubtams, I am sorry you’re having trouble. Unfortunately I am not quite sure what exactly you are doing here as it seems you have skipped all the information the forum template is asking for when posting a new questions.
Which version of n8n are you using? How exactly are you writing your files to disk? Any particular reason you are using the Read Binary File seeing you already have the binary files in n8n?
Thanks @ubtams! Seeing your data is already in n8n you wouldn’t need the Read Binary File node (which would simply read files from your filesystem). Your JSON file could for example be processed by the Move Binary Data node instead if you want to access its content in n8n.
