Hey there, I am using a server with Rasa X (V. 0.35.0) on it and I connected to my git repo. It loaded everything necessary and I am able to push my changes to git. But if I click on discard changes, I get a 404 Error and the status stays yellow. Furthermore if I chance the nlu.yml in my IDE and push it to my git repo, Rasa X does not see the changes - it stays green. I already tried to restart the pods and disconnected and reconnected to the git repo. This is my error-message ``` rasa-x_1 | Job "run_background_synchronization (trigger: cron[minute='*'], next run at: 2021-01-25 17:14: 00 UTC)" raised an exception rasa-x_1 | Traceback (most recent call last): rasa-x_1 | File "/usr/local/lib/python3.8/dist-packages/apscheduler/executors/base.py", line 125, in run_job rasa-x_1 | retval = job.func(*job.args, **job.kwargs) rasa-x_1 | File "/usr/local/lib/python3.8/dist-packages/rasax/community/services/integrated_version_con trol/git_service.py", line 131, in run_background_synchronization rasa-x_1 | loop.run_until_complete(git_service.synchronize_project(force_data_injection)) rasa-x_1 | File "uvloop/loop.pyx", line 1456, in uvloop.loop.Loop.run_until_complete rasa-x_1 | File "/usr/local/lib/python3.8/dist-packages/rasax/community/services/integrated_version_con trol/git_service.py", line 1114, in synchronize_project rasa-x_1 | return await self._force_inject_latest_remote_changes() rasa-x_1 | File "/usr/local/lib/python3.8/dist-packages/rasax/community/services/integrated_version_con trol/git_service.py", line 1174, in _force_inject_latest_remote_changes rasa-x_1 | await self._inject_data() rasa-x_1 | File "/usr/local/lib/python3.8/dist-packages/rasax/community/services/integrated_version_con trol/git_service.py", line 1146, in _inject_data rasa-x_1 | await rasax.community.initialise.inject_files_from_disk( rasa-x_1 | File "/usr/local/lib/python3.8/dist-packages/rasax/community/initialise.py", line 350, in in ject_files_from_disk rasa-x_1 | inject_domain( rasa-x_1 | File "/usr/local/lib/python3.8/dist-packages/rasax/community/initialise.py", line 185, in in ject_domain rasa-x_1 | if not rasa.shared.core.domain.Domain.is_domain_file( rasa-x_1 | File "/usr/local/lib/python3.8/dist-packages/rasa/shared/core/domain.py", line 1582, in is_d omain_file rasa-x_1 | content = rasa.shared.utils.io.read_yaml_file(filename) rasa-x_1 | File "/usr/local/lib/python3.8/dist-packages/rasa/shared/utils/io.py", line 368, in read_yam l_file rasa-x_1 | return read_yaml(read_file(filename, DEFAULT_ENCODING)) rasa-x_1 | File "/usr/local/lib/python3.8/dist-packages/rasa/shared/utils/io.py", line 349, in read_yam l rasa-x_1 | return yaml_parser.load(content) or {} rasa-x_1 | File "/usr/local/lib/python3.8/dist-packages/ruamel/yaml/main.py", line 343, in load rasa-x_1 | return constructor.get_single_data() rasa-x_1 | File "/usr/local/lib/python3.8/dist-packages/ruamel/yaml/constructor.py", line 113, in get_s ingle_data rasa-x_1 | return self.construct_document(node) rasa-x_1 | File "/usr/local/lib/python3.8/dist-packages/ruamel/yaml/constructor.py", line 123, in const ruct_document rasa-x_1 | for _dummy in generator: rasa-x_1 | File "/usr/local/lib/python3.8/dist-packages/ruamel/yaml/constructor.py", line 723, in const ruct_yaml_map rasa-x_1 | value = self.construct_mapping(node) rasa-x_1 | File "/usr/local/lib/python3.8/dist-packages/ruamel/yaml/constructor.py", line 440, in const ruct_mapping rasa-x_1 | return BaseConstructor.construct_mapping(self, node, deep=deep) rasa-x_1 | File "/usr/local/lib/python3.8/dist-packages/ruamel/yaml/constructor.py", line 255, in const ruct_mapping rasa-x_1 | value = self.construct_object(value_node, deep=deep) rasa-x_1 | File "/usr/local/lib/python3.8/dist-packages/ruamel/yaml/constructor.py", line 146, in const ruct_object rasa-x_1 | data = self.construct_non_recursive_object(node) rasa-x_1 | File "/usr/local/lib/python3.8/dist-packages/ruamel/yaml/constructor.py", line 181, in const ruct_non_recursive_object rasa-x_1 | data = constructor(self, node) rasa-x_1 | File "/usr/local/lib/python3.8/dist-packages/rasa/shared/utils/io.py", line 311, in env_var_ constructor rasa-x_1 | raise ValueError( rasa-x_1 | ValueError: Error when trying to expand the environment variables in '${{ github.event_name == 'push' }}'.
