Hi,

It seems same as the following. For now, can you save it then restart Studio?

Action ambiguous

Today, I have suddenly an issue with my attended robot. On several activities I get this error: [image] This is the case for simple activities like assign, input dialog… I tried to use different versions of packages but this don’t help. I also tried with a backup version of the robot and it gives the same problem. Another robot is OK, so the problem is dedicated to the one robot. These are the used packages: [image]

Hi,

According to the above topic, it repairs by changing version. And the latest Studio has automatic recovery feature.
So for now can you try to save all the xaml files then reopen Studio, and upgrade or downgrade M365 package and/or Mail package to some version.

Hey,

HI @NewBiew @elasri.omayma1 ,

Can you share your project? It’s no problem dummy project if we can reproduce this issue.

It means there are two imported namespaces that have an .Action method. So it doesn’t know which one you want to use. For example, say we have two namespaces with .Action:

system.SomePackage.SomeClass.Action
system.AnotherPackage.SomeClass.Action

It doesn’t know whether to use system.SomePackage or system.AnotherPackage to execute SomeClass.Action

So you need to specify the entire namespace. In this case it’s telling you the two .Actions are…

System.Action
Microsoft.Office.Interop.Outlook.Action

So you need to type the entire namespace not just Action

Hi,
My project:
Main.xaml (124.3 KB)

HI,

If possible, can you share your project including project.json etc. as zip file because single xaml file doesn’t have version information for activities package?

Regards,

[NewBiew]

Hi,
zip my project:
Main.zip (15.8 KB)

[Yoichi]

Hi

I re-create new project which has same dependencies for activities package, then port it from your original project. Can you check if this works in your environment?

Hi, It works. Many thank for your support.
can you tell me where the error is coming from?

[Yoichi]

HI,
Thank you for checking.
Further investigation, it seems to be caused by the following element : <x:String>Microsoft.Office.Interop.Outlook</x:String>

For now, can you try to remove the above element your original Main.xaml using text editor, then check if it works?

(please back up the Main.xaml before do it)
