"Network Error when using Patch function: The requested operation is invalid" - PowerApps Form

[professor_proto]

Hello all, I hope you are well. 

I am facing an issue. I currently have a drop down list connected to a "office 365 user" data connection to allow for searching within the organisation. It all seems to be working well, however when I attempt to submit this form to the SharePoint website including this field, I get this error:

"Network Error when using Patch function: The requested operation is invalid"

I have honestly felt like I've tried everything and can't manage to make it click. When I do not include that specific field in the submission, the form submits just fine leading me to believe that this is the cause. 

I welcome any ideas. 

Regards,

Professor P

How are you patching the Office365User to the People field, it needs a specific format during patching for complex SharePoint fields:

PersonFieldNameGoesHere: 
   {
     '@odata.type': "#Microsoft.Azure.Connectors.SharePoint.SPListExpandedUser",
      Claims: Concatenate("i:0#.f|membership|",YOUROFFICE365USEREMAIL_HERE),
      DisplayName: YOUROFFICE365USERNAME_HERE,
      Email: YOUROFFICE365USEREMAIL_HERE
    }

Hi ManCat, thanks for your reply. 

I am a bit of a PowerApps newbie, could you please help me understand the code above? 

And this is the code I am currently using in the drop down box:

Oh hey, well we all gotta start somewhere 🙂

So, where are you patching this data? I'd like to see the patch statement that your error is referring to.

And if you're not using a patch, and just using the form submit, then I'd like to see your datacard's Update value, as that may be pointing to the wrong thing.

If you could explain a bit more about where the dropdown is located [in a datacard in a form, outside a form, etc] and is there a field in your datasource that can accept that dropdown value?

The more information you can provide the easier it will be to help 🙂

Hi again ManCat, thanks for your help so far. 

I've just tinkered with the form a bit and realised that the error with the 'patch' function, had been because the field (an therefore column) in the SharePoint list had been a multiple choice field, rather than a people/group field (I assume it had difficulties storing the value in a choice field). The issue is now solved, thank you 🙂

Awesome, thanks for coming back and confirming, I'll mark your reply as the answer! 🙂
