How to suppress warning when Nunjucks template does not exist?

Question

When calling nunjucksEnvironment.render(“does-not-exist”, context) an error is thrown.

How can I suppress that error? Alternatively, how can I check to see if a template exists before calling .render using whatever template loader is being used to resolve the template?

I am able to wrap the calling of the render method within a try/catch statement but I don’t want to eat all templating errors.

nunjucksEnvironment has getTemplate method, i guess you could wrap it to check that template exist.

function hasTemplate(templatePath) {
  try {
    nunjucksEnvironment.getTemplate(templatePath);
    return true;
  } catch {
    return false;
  }
}
