Can't create a nested many To many properties - prisma

Question

I've been stuck on this problem for hours.
I'm trying to create an object linked by a many to many relationship.
However, I get this error when the function is invoked:
Unknown arg 0 in data.merchandises.create.0 for type ListingsMerchandisesCreateWithoutListingInput.
Argument merchandise for data.merchandises.create.merchandise is missing.
I don't know where that "0" comes from.
Thank you in advance for your help..

concerning schema:

model ListingsMerchandises {
listingId Int
listing Listing #relation(fields: [listingId], references: [id])
merchandiseId Int
merchandise Merchandise #relation(fields: [merchandiseId], references: [id])
##id([listingId, merchandiseId])

I tried several formats, I even tried a connect but without success.
No type errors are thrown
