Updating Enterprise Project Type from Project Online

I am a Power Apps developer and I have just started using Power Automate.  I am able to create a new Project from within Power Apps.  What I am unable to figure out is how to update other native fields besides the Project Name, Project Owner and Project Description.  I specifically need to update the Enterprise Project Type Name value as well as custom field Task1.


I am using the Send an HTTP request to SharePoint step in my flow.  


Since I could not find the GUID for an internal native field I tried the GUID for a custom field defined as a text field.  This is the error that I received.

Hi @DDucolonSBUX,


Please have a try that removing the flow from the power apps control and then add it again over there.

You have a couple of questions in this one topic so I'll see if I can help with some.

Enterprise Project Type does have a GUID.  Gear, PWA Settings, Enterprise Project Types, Select the one you want to look at, then go to the very bottom and expand System Identification Data

Not real sure what the objective is but at least you can have where to find the guid and you can try your command.


Second item is with Enterprise Custom Fields.  I was able to get a bunch of these to work using updateTextProperty or updateCurrencyProperty or updateNumberProperty.  here is an example of one of mine.


I started with "value":"This is gonna be really great"} and then started manipulating the body() command from my array to get what I wanted.

Your error looks like it might be something different than those hints I provided above but maybe by having the answers above it might work.  It looks to me like you might be trying to execute MS Project commands against a Sharepoint site instead of a Project Server/Online site??
