Getting 405 Method not found error when tying to update VCAC model entity

Hello all.

I am trying to run the workflow 'Update a VCAC model entity' from within another workflow.

I am able to succesfully read the required entity(s) from 'Read a VCAC entity by custom filter', then choose the appropriate entity, pass it to the 'Update' workflow.

But when executing the last part, I am getting the '405 Method not allowed error'.

The entity set I am trying to access is 'PropertyAttributes'.

What I am doing wrong? Thanks
