### dbt version update in Automation Cloud

The dbt versions used in Automation Cloud for Process Mining have been updated. Following this update, warnings may appear in your ingestion logs even when ingestions complete successfully.

You may see a warning similar to the following:

```
[WARNING][MissingPlusPrefixDeprecation]: Deprecated functionality
Missing '+' prefix on `materialized` found at `uipathCustom.materialized` in
file `/tmp/Afs2QD/sources/dbt_project.yml`. Hierarchical config values without a
'+' prefix are deprecated in dbt_project.yml.
```

These warnings do not affect ingestion results — your data continues to be processed correctly.

To suppress the warning, update your `dbt_project.yml` file by adding a `+` prefix to the affected property. For example, change `materialized` to `+materialized`:

```yaml
models:
  uipathCustom:
    +materialized: table
```

This aligns your configuration with the current dbt standards and prevents the deprecation warning from appearing in future ingestion runs.
