Resolution

* it is possible that one or several agreement attribute template or document attribute template have been removed in B2Bi UI, but whereas they were in use in an Agreement or a Document Agreement

* when the agreement is executed, the PM Server does not find the attribute template and throws the error

* restart B2Bi so that the deletion of the attribute will complete
