Hey guys, here is my code for a PowerApp that will display in a gallery every item that match the filter condition. The app as been working for so long, but now it just wont work anymore. The error (Error while trying to retrieve data from the network: Fetching items failed. Possible invalid string in filter query. clientRequestId: beabf3bf-5b0a-4bdf-8d18-e31d401d2ae3 serviceRequestId: 519c9ca1-9064-8000-b883-afcabba06da0) happens when the ComboBox 'dus_3' isn't blank and a choice of dus is selected. If the ComboBox is left blank everything works.



*** FYI : This code is written on a french platform of PowerApp so all ';' are equals to ','



Thanks in advance ! :)

SortByColumns(
    Filter(
        demandeEchange;
        journee <= end_date_1.SelectedDate;
        journee >= start_date_1.SelectedDate;
        IsBlankOrError(statut);
        dus_3.Selected.Nom_DU = Blank() Or dus_3.Selected.Nom_DU = LookUp(
            Employee;
            Title = Nom_agent;
            key_DU
        ) Or dus_3.Selected.Nom_DU = LookUp(
            Employee;
            exportAgent1 = Nom_agent;
            key_DU
        );
        agents2.Selected.Nom_agent = Blank() Or agents2.Selected.Nom_agent = Title Or agents2.Selected.Nom_agent = exportAgent1
    );
    "journee";
    SortOrder.Ascending
)

Hey @WarrenBelz thanks for your reply !

Yes I am using SharePoint, in the end I went back into my SharePoint List and change the data from Title column to a new column "Name" and then it worked whithout any problem. I had to redo my code in all the app for the Title column, but yeah it was the Title column from the Sharepoint list that was causing the error.

Hi @OP-04081924-0

Firstly, can you please remember to post your code in Text - saves re-typing here. The code below is OCR'd, so watch spelling. Try this for a start - also helps with Delegation (I assume you are using SharePoint)
With( { _Data: SortByColumns( Filter( demandeEchange; journee <= end_date_l.SelectedDate; journee >= start_date_l.SelectedDate; statut = Blank(); agents2.Selected.Nom_agent = Blank() Or Title = agents2.Selected.Nom_agent Or exportAgentl = agents2.Selected.Nom_agent ) ); _DUS3: dus_3.Selected.Nom_DU }, Filter( AddColumns( _Data; LU1: LookUp( Employee; Title = Nom_agent ).key_DU; LU2: LookUp( Employee; exportAgentl = Nom_agent ).key_DU ); _DUS3 = Blank() Or LU1 = _DUS3 Or LU2 = _DUS3 ) )
