Missing required parameter from for method open

[Darryl1674]

Hi,

Have upgraded my machine to MacOS BigSur and updated to InDesign 2021 and whenever I attempt to open an .indd or .idml from the desktop, InDesign pops up this dialog box. 

I see I'm not alone with this issue as I see a couple of other threads that mention the same issue.  Is it an issue with InDesign or Big Sur?

I personally don't use BigSur so far but have not seen this issue reported by the people I know use InDesign and BigSur. Can you provide the following information

• Does the file path have any special characters?
• What happens if you create a file, save it and then try to open it, does it still fail to open?
• Does it happen only to files saved on the Desktop?
• Do you have any third party plugin or script installed on your InDesign? If yes try by removing those

Hi Manan,

1. No special characters in the file path
2. Yes, it still fails to open if I open them from Finder or the Desktop
3. All files regardless of location
4. No extra scripts or plugins

What code do you use to open a file?

[Darryl1674]

Hi Peter,

I'm not sure what you mean by code?  All I'm doing is double clicking or dragging the file onto the dock icon

Sorry, I thought you were trying to open a file using a script. I was wrongfooted by the title of the topic.

On the Mac, the Open gesture (double-click a file etc.) translates to an open "AppleEvent" - the basic operation also used by an AppleScript.

This could be an issue with security :clown_face: in Cupertino overdoing it recently.

Have a look at System Preferences >> Security & Privacy >> Files and Folders, if there are any restrictions on InDesign. While I have no particular InDesign entry there, I have InDesign listed in the "Full Disk Access" next door.

THANK YOU, Dirk.  That was indeed the problem.  InDesign wasn't allowed to access our network volumes.  All sorted now
