Fitbit made an adjustment on their side and the issue is fully resolved

We've identified an issue causing increased errors when syncing nutrition data from Fitbit, resulting in "500 Internal Server Error" entries appearing in client logs. The issue is due to recent unexpected changes in Fitbit's nutrition data format. Our engineering team is actively working on an update to handle these changes. We've reached out to Fitbit for clarification and are monitoring the situation closely. We will provide further updates as new information becomes available. Thank you for your patience.
