After making a roll and saving it, power bi hangs.

Goedmorning.

Im using pipeline in fabric  en  I want to pass parameters to a nootbook T-SQL , 

what is wrong hier :

from pipeline parameters

Bestand

IcrField

IncDatum

{
"notebookId": "599ed485-5c5e-4ef6-8622-bb0739d1c35d",
"workspaceId": "d0a12fde-ef49-45c6-934a-b898d14a0916",
"parameters": {
"Bestand": {
"value": "BEROEP",
"type": "string"
},
"IcrField": {
"value": "MUTATIEDATUM",
"type": "string"
},
"IncDatum": {
"value": "2024-09-14T00:00:00Z",
"type": "string"
}
}
}

DECLARE @Bestand VARCHAR(20);
SET @Bestand = {Bestand}; -- Substitute parameter safely, e.g. "BEROEP"

DECLARE @IcrField VARCHAR(20);
SET @IcrField = {IcrField}; -- Substitute parameter safely, e.g. "MUTATIEDATUM"

DECLARE @IncDatum DATETIME;
SET @IncDatum = CAST({IncDatum} AS DATETIME); -- Convert string to DATETIME, e.g. '2024-09-14T00:00:00Z'

PRINT @Bestand;
PRINT @IcrField;
PRINT @IncDatum;

i used de paramers of diferent  sintaxi, but every time get errors.

is another way to define de parameter in de Nootboek T-SQL? 

this is de error;
