Expected Exception during execution

[DaspawnW]

I have a custom helm chart post renderer https://github.com/DaspawnW/vault-crd-helm-renderer that receives a valid helm chart with some jinja2 templates and performs vault lookups to replace those lookups with real values out of HashiCorp Vault.

By accident we detected today that Jinjava doesn't enforce a strict mode by default. If you provide an expression that is invalid like this one:

String content = "{{ vault.lookupV2('kv-test/credentials', 'username) }}"

jinjava().renderForResult(content, context);

I would expect that Jinjava now fails as it doesn't contain the last "'", but it seems that the rendering continues and everything that happens after this invalid expression now fails to render properly.

Is there a way to enforce Jinjava to be in a strict mode?

Please see below a testcase where I would expect that it fails when the expression is wrongly written:

import com.hubspot.jinjava.Jinjava;
import com.hubspot.jinjava.JinjavaConfig;
import com.hubspot.jinjava.interpret.RenderResult;
import com.hubspot.jinjava.interpret.TemplateError;
import org.junit.jupiter.api.Assertions;
import org.junit.jupiter.api.Test;

import java.util.HashMap;
import java.util.List;

class TestClass {

    public String hello(String msg) {
        return "test" + msg;
    }

}

public class InvalidJinja {

    public Jinjava jinjava() {
        JinjavaConfig config = JinjavaConfig
                .newBuilder()
                .build();
        Jinjava jinjava = new Jinjava(config);
        return jinjava;
    }

    @Test
    void shouldFailToRender() {
        HashMap<String, Object> context = new HashMap<>();
        context.put("test", new TestClass());

        String content = "{{ test.hello('world) }}";
        RenderResult renderResult = jinjava().renderForResult(content, context);

        List<TemplateError> errors = renderResult.getErrors();

        System.out.println(content);
        Assertions.assertEquals(1, errors.size());
    }

}
