I am using the desktop version, and I am trying to create a flow to compress and zip multiple files into a single zip file, and getting error message saying unable to compress file (Chinese Text). I am wondering if anyone has encountered same problem, and know a solution. And funny thing is if I change to just single file, then it works fine.

For me it worked fine when I just select file and selected multiple files from the same folder (Hold CTRL and select the files you want)

Looks like your syntax might be bit wrong when I compare it to mine:

My Zip files -action:

Zip files -action looks like this:

Thanks for speedy reply. And I will sure correct the code. However, I did use the selection with control to select multiple files and the code was generated automatically. Thanks for the update and I will repost here if I get it to work.

Now your Files(s) to zip seems to be a string value and not an array:

For reference how string vs array looks like in PAD:

Is your flow perhaps Power Fx enabled flow? If so I would suggest you create a new flow with Power Fx not enabled.

I quickly tested and seems like Power Fx enabled flow has this bug. Its in preview so has many bugs still.
Seems like it still uses % -signs with the array reference in Zip files even though Power Fx doesn't actually use % -signs for referencing (it uses equal sign)

If you really need to use Power Fx -enabled flow then use Get files in folder -action first to list the files you want to zip.
Then use that variable in Zip files:

Then it worked for me.

Indeed, that was early Thanksgiving gift !

I tried new flow, disable Power Fx, and it worked.

That was 12 hours, I can't get back from Microsoft.

Thanks a whole bunch :)
