Contracts approval error

Content

Hi, 

When I submit a specific type of contract for approval this error:

"Error occurred while displaying History tree table. Error in evaluating routing slip. Check the underlying exception and correct the error in the routing slip"

I'm using the rule:

if
ContractDetails.contractTypeId equals 300000023330306
then
List Builder: Resource
Response Type: Required
Participants
Users: "braulio"
Groups: null
Application Role: null
Rule Name: "Rule1"
Dimension Id: null

I've tested with other rules but they all give the same error. This contract is of the Enterprise Contracts class.

I have other types of contracts that are generating approval normally, only they are of the Agreement class.
