# Step 6: Error 1

In troubleshooting Step 1 we resolved all of the errors associated with `pylithapp.cfg`.
In this example, we expect all errors to be associated with inputs files specific to Step 6, such as `step06_twofaults.cfg`.

## Error Message

```

## Troubleshooting Strategy

We have several configuration errors, so we start with the first one at lines 3-6.
Spatial databases require a description, and PyLith cannot find one for `timedependent.interfaces.faultcohesivekin.singlerupture.kinsrcstep.simpledb`.
We examine the fault parameters for `step06_twofaults.cfg` and see that `db_auxiliary_field` for the earthquake rupture is missing the description.

## Resolution

```{code-block} cfg

[pylithapp.problem.interfaces.fault.eq_ruptures.rupture]
...
db_auxiliary_field.description = Fault rupture for main fault
