+
+Flag to bypass Pydantic validation errors by patching the parser to ignore extra fields.
+
+This option is useful when working with newer dbt versions that introduce fields not yet supported by the `dbt-artifacts-parser` library. When enabled, the parser will ignore unknown fields instead of raising validation errors, allowing you to continue generating ERDs even with newer artifact schemas.
+
+> Default to `False`
+
+!!! info "When to use this option"
+    You might encounter Pydantic validation errors like `"Error: Could not open file 'catalog.json': File catalog.json is corrupted, please rebuild"` when using artifact files from newer dbt versions. In such cases, enabling this flag can help you work around compatibility issues while waiting for the parser library to catch up with the latest dbt schema changes. Just be aware that any unsupported fields won't be included in the generated ERD (which is usually fine since relationship information remains intact).
+
+**Examples:**
+=== "CLI"
+
+    ```bash
+    dbterd run --bypass-validation -mv 12 -cv 1
+    ```
+
