Posted on by Ziby

I would like to use flow to set item permission based on multiple metadata.

everything works ok but inside apply to each i get values inside square brackets and that's why i get an error.

The expression "lists/getByTitle('Enterprise')/items(['284'])/roleassignments/addroleassignment(principalid=['132'],roledefid=1073741826)" is not valid.
clientRequestId: 11a0d4e2-9c13-41a1-a222-797f3193c689
serviceRequestId: 01d6f39f-8048-c000-89d5-8857e0799846

How to enter that without brackets. Ideas please 😄

Re: Flow for setting up item permission over REST API

Hi @Ziby,

In your example the Uri would be:

_api/web/lists/getByTitle('Enterprise')/items(284)/roleassignments/addroleassignment(principalid=132,roledefid=1073741826)

Below is an example of such a setup in a Send an HTTP request to SharePoint action.

Keep in mind that this only works if inheritance is already broken on the item and it already got unique permissions.

Re: Flow for setting up item permission over REST API

Sorry i will try to explain that a little bit more 😄

So we have Sharepoint document library with column "product". Type is choice and we allow multiple selection.
we also have Sharepoint groups with exactly the same names as the product field values.

I created flow which starts when istem is created, then it clears permission on item
Since we use multiple selection i can use only Apply to each.
And after test i get an error

The expression "lists/getByTitle('Enterprise')/items(['284'])/roleassignments/addroleassignment(principalid=['132'],roledefid=1073741826)" is not valid.
clientRequestId: 44c91033-1c4c-4535-9fee-54e082a0761b
serviceRequestId: b8daf39f-509a-c000-5e6c-afe2edeb61b9

The cause for that error is that the values ItemID and GroupID are in Square Brackets and REST api
do not allow such values.

Do you have some idea how set that without brackets

Thanks

Hi @Ziby,

Even with your setup you shouldn't need to put brackets around the ItemID and GroupID variables. They are just numbers, the REST API should be able to handle those without the [' '].

So, in your setup it would be like this. Can you try this instead?

_api/web/lists/getbytitle('Enterprise')/items(@{variables('ItemID')})/roleassignments/addroleassignment(principalid=@{variables('GroupID')},roledefid=1073741826)
