Adding date and time fails the flow

Before the Flow worked great. The file name would always stay the same and I wanted to add a time stamp. I added this function

"formatDateTime(utcnow(),'Pacific Standard Time''MM-dd-yyyy hh:mm tt')" and now the flow fails, I also added .xlsx to the end thinking that was the problem. This function works on my other flows, what am I missing?

I think the format DateTime function returns time with a colon in it which can not be used in filenames. It's a special character. I put together the following expression. Can you try it?


replace(replace(convertFromUtc(utcNow(), 'Pacific Standard Time'), ':'''), '.''')

@PrasadAthalye First, thank you for responding. Previously my function worked to timestamp files and produced "filename 04-04-2021 11_30 PM.xls" now it fails, with your code it produces "filename.xlsx2021-04-0409321199445922 "

I figured out what the problem was, my previous file creations needed me to build the file name and I could add in functions and finish it off with .xls.


This flow is different I see, it creates the entire file name. I got around this by placing this function prior "convertTimeZone(utcnow(),'UTC','Pacific Standard Time','MM-dd-yyyy hh:mm tt')"
