Getting 405 Method not found error when tying to update VCAC through VCO workflows

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' from the IIS (the Windows machine running IAAS service).

Even the standard workflow 'update blueprint property' also fails with same error.

Is there some configuraiton issue with IIS server?

Thanks
