Since yesterday, the format for a LookupId field in SharePoint must be in string format and not integer, why?
Body sample before yesterday:
{
"fields": {
"TravailEffectue": "Préparation et chargement EP",
"CollaborateurLookupId": 12,
"Duree": 120,
"Date": "2023-05-12",
"InterventionLookupId": 400
}
}
and now:
{
"fields": {
"TravailEffectue": "Préparation et chargement EP",
"CollaborateurLookupId": "12",
"Duree": 120,
"Date": "2023-05-12",
"InterventionLookupId": "400"
}
}
This change in the Graph API crash my mobile app !
Why for an ID Microsoft change the Graph API from Interger to String ?

I can confirm the behavior mentioned. The Graph API suddenly doesnt accept LookupIds as Integer anymore. This must be a recent change, since it worked for years like this until end of last week. This makes many solutions crash!
Update 16.05.2023: This Error no longer persists. Maybe Microsoft reverted the change of the Graph API (for good)
Hi Pierre-Yves Rosat & Bryan Lottes,
Thanks for your reply. As mentioned below, the default properties of id & sharepointIds are of datatype "string" using the site resource type for the methods mentioned.
Please use the recommended datatype referenced via the documentation to avoid any unexpected results.
