I'm using the demo notebook 'TimeseriesDemo.ipynb' to try and get Sentinel-1 timeseries. However, upon running requests.get(''https://services.terrascope.be/timeseries/v1.0/ts/''), I get an error code 500 and the following error message: "unknown OpenSearch collection BCGMS_NDVI300". I did not change anything in the notebook, so I'm confused as to why I am receiving this error. Can you help me solve this issue? Thanks!
