I have a Google App Engine application with jinja2, when I force a 404 error, I have this error:
errors/default_error.html Traceback (most recent call last): File "/base/python27_runtime/python27_lib/versions/third_party/webapp2-2.5.1/webapp2.py", line 1536, in __call__ rv = self.handle_exception(request, response, e) File "/base/python27_runtime/python27_lib/versions/third_party/webapp2-2.5.1/webapp2.py", line 1596, in handle_exception return handler(request, response, e) File "/base/data/home/apps/s~sandengine/latest.360189283466406656/main.py", line 28, in handle_404 t = jinja2.get_jinja2(app=app).render_template(template, **c) File "/base/python27_runtime/python27_lib/versions/third_party/webapp2-2.5.1/webapp2_extras/jinja2.py", line 158, in render_template return self.environment.get_template(_filename).render(**context) File "/base/python27_runtime/python27_lib/versions/third_party/jinja2-2.6/jinja2/environment.py", line 719, in get_template return self._load_template(name, self.make_globals(globals)) File "/base/python27_runtime/python27_lib/versions/third_party/jinja2-2.6/jinja2/environment.py", line 693, in _load_template template = self.loader.load(self, name, globals) File "/base/python27_runtime/python27_lib/versions/third_party/jinja2-2.6/jinja2/loaders.py", line 115, in load source, filename, uptodate = self.get_source(environment, name) File "/base/python27_runtime/python27_lib/versions/third_party/jinja2-2.6/jinja2/loaders.py", line 180, in get_source raise TemplateNotFound(template) TemplateNotFound: errors/default_error.html
Here is my yaml file:

code:
def handle_404(request, response, exception): c = { 'exception': exception.status } template = config.error_templates[404] t = jinja2.get_jinja2(app=app).render_template(template, **c) response.write(t) response.set_status(exception.status_int) app = webapp2.WSGIApplication(debug = os.environ['SERVER_SOFTWARE'].startswith('Dev'), config=config.webapp2_config) app.error_handlers[404] = handle_404 routes.add_routes(app)
Configuration file:
error_templates = { 404: 'errors/default_error.html', 500: 'errors/default_error.html', }
Here is the folder structure
Another important thing is that it works without problems on the local machine (SDK), but the problem arises in production
You can learn the full code because it is open source Thanks in advance for your help.
