Get ListItemAllFields after added file to a folder

[pINKmUNster]

Hello,

I'm trying to add list item field while adding a file.
I saw that i can use the ListItemAllFields property but when I try to add a new value in it my code failed.

I have this error

PnP.Core.ClientError
PnP.Core.ClientException: Please first fetch this list from SharePoint before doing operations on it
  at PnP.Core.Model.SharePoint.ListItem.BuildUpdateApiCallAsync(PnPContext context)
  at PnP.Core.Model.SharePoint.ListItem.BaseUpdate(Func`2 fromJsonCasting, Action`1 postMappingJson)
  at PnP.Core.Model.BaseDataModel`1.UpdateAsync()

This my dummy code :

var addedFile = await folder.Files.AddAsync(fileName, stream);
addedFile.ListItemAllFields["aaa"] = "aaaaa";
await addedFile.ListItemAllFields.UpdateAsync();

Do I need to recatch the file and load the ListItemAllFields or do i'm missing something?

Thanks 😃

You'll need to load ListItemAllFields that property is not expanded when doing an add. Add this line after the AddAsync call:

await addedFile.ListItemAllFields.LoadAsync();

It's working as expected.
Thank a lot
