Invalid data: Expected arguments but found none

Does someone knows upon deployment (dfx deploy) why and when the error Invalid data: Expected arguments but found none. can occur?

I don’t have any particular stacktrace about it, don’t notice any particular error in my console and it happens randomly, means same builds are also successful.

Check the actor constructor of the canister that you are going to deploy/install. If there are arguments inside, you have to add the --argument flag with the values.

Yes indeed, forgot to close this question. Thanks for your hint!

The solution finds place in Encode Principal to Candid arguments - #10 by peterparker and Encode Principal to Candid arguments - #7 by peterparker

dfx deploy not running.help with this.

What happens if you try the above solution?
