Must provide either 'fields' or 'layoutTypes' on a flow screen lookup

Question

I'm trying to build a flow with a lookup component. However, I'm always getting the error :

Must provide either 'fields' or 'layoutTypes' when providing childRelationships param.

Here are the parameters of my flow component.

It seems that all field API Name, Object API Name and RecordId fields are OK, as I doubled checked it.

Do you have any idea about why this error arises ?

Answer 1

I had this same issue but without lookup filters. What I had to do for the record Id was use a variable to get the record providing the existing value then reference the field that has the value I wanted. Just referencing the recordId didn't work.

So, for example, say you have a variable that gets the Customer__c called getCustomer to get the reference record. For Record Id you'd enter {!getCustomer.Billing_Contact__c}
