1. Is this request related to a challenge you're experiencing? Tell me about your story.

I want to create a file like csv or other format, but when I try open("xxx.txt", "w") and write() I got error like permission denied wherever I place the temp file(tried /tmp /var/sandbox/sandbox-python/tmp/ /var/sandbox/xxx)
I want to know if I can create a custom file by script and then download?

2. Additional context or comments

I also tried to download a file directly via workflow, but I failed to pass file object via Code and got error Object of type File is not JSON serializable(it will success only in start->answer which contains only 2 components and the file passed directly, if I add a code component between then , the error occured)
