Cannot access Sharepoint Document Library in Flow after using custom permissions, even though my account has Full Control

Good day. 

 

I have a Power Automate flow that is reading and creating a new file to a sharepoint document library. 

by default , the flow runs perfectly with site level permissions, and the account that im using to execute the sharepoint connectors is a member of the Site Owner group.

 

Now i need to have custom permissions on that document library , so members cannot access it, only owners ( full control ), and visitors ( Read only ).  after enabling unique permissions in the library, i only removed the Members group. so now it is like this, with my account that has full control.

In my power automate flow, i edited the flow and in my sharepoint get files / create file actions, it can still lookup at that document library using my same account.  

 

But the problem is when i run the flow, i am getting and error saying access is denied. even though my account has still full control on the library.

i tried recreating this action and another create file action, i still get the error after running.

but when i remove unique permissions in the library, my workflow runs successfully. 

 

I am confused why this happens. 

Can anyone help me how to go around with this issue? cause i believe it shouldn't behave this way since my account has Full Control on the document library. 

 

Hoping for anyone's help. 

 

Thank you very much.

    Hi there, 

    I think we need to know the specifics of your unique permissions .. for example ... do the folders / files within also have unique permissions?
