Not able to execute policy
## Description:
The Task service can not execute a policy.
## Steps to reproduce:
- make a call to the task service using the [didResolver](https://gitlab.eclipse.org/eclipse/xfsc/tsa/policies/-/blob/main/example/didResolve/1.0/policy.rego?ref_type=heads) policy `curl --location '{URL}/tsa/task/v1/task/didResolve' \ --header 'Content-Type: application/json' \ --data '{ "did": "did:key:z6Mkfriq1MqLBoPWecGoDLjguo1sB9brj6wT3qZ5BxkKpuP6" }'`
- get the taskID and make a call to get the result `curl --location '{URL}/tsa/task/v1/taskResult/{taskID}'`
### Expected result:
```json
{
"kty":"OKP",
"crv":"Ed25519",
"x":"FN5URrQRnKSaEjQvC8e6vpNGxivoocgPLgmzv_5JH2k"
}
```
### Actual result:
```json
{
"id": "...",
"kind": 5,
"message": "task is not found"
}
```
### Logs:
```json

"caller":"executor/worker.go:73",
"msg":"error executing task",

}
