+You can use `error_mode` to configure how to response to errors. `jekyll-diagrams` respect the global [liquid options](https://jekyllrb.com/docs/configuration/liquid/):

+```

+Avaliable options:
+
+- `lax`: Ignore all errors
+- `warn`: Output a warning on the console for each error
+- `strict`: Output an error message and stop the build
+
+You can also override it for just `jekyll-diagrams`:
+
+```yaml
+jekyll-diagrams:
+  error_mode: 'mode'
