nameToID -610 ERR_ILLEGAL_DS_NAME on trying to right to source attribute

I written a rule in a loop back driver and I am trying to set a source attribute value but getting the following error. Accounts do not have associations to this driver and based on the way we have written it, they will not have associations. See trace snippet below.
