getting error "prisma:error Must call super constructor ..." at a simple insert

So, I get this error "prisma:error Must call super constructor in derived class before accessing 'this' or returning from derived constructor" when doing this insert:

const form = await prisma.forms.create({
            data: formData
        });

const form = await prisma.forms.create({
            data: formData
        });

The formData looks like this:

const formData = {
userId,
isComplete: false,
treatmentType: user?.treatmentType || TREATMENT_TYPE.TBD,
isArchived: false,
formType: 'Youth',
isCaregiver: !!isCaregiver,
...(sessionId && { sessionId })
        };

const formData = {
userId,
isComplete: false,
treatmentType: user?.treatmentType || TREATMENT_TYPE.TBD,
isArchived: false,
formType: 'Youth',
isCaregiver: !!isCaregiver,
...(sessionId && { sessionId })
        };

And the model in schema has all those fields and then some

The

prisma

prisma

variable seems to be instantiated&configured correctly, because this query, which is in the same function, above the erroring one, returns successfully:

const user = await prisma.users.findUnique({
            where: { id: userId }
        });

const user = await prisma.users.findUnique({
            where: { id: userId }
        });

.

Now github's copilot and gemini from Microsoft couldn't come up with a working solution/workaround, and neither did google search results.

Do you have any ideas what could be wrong or how I can fix this?
