Need Help with Dynamic Folder Strcuture for Files Loaded to a LakeHouse

Hi kewaynes333 
Error Property ‘tableName’ doesn’t exist:
The error message indicates that the property tableName does not exist in the current context. The available properties are ‘dateSold, propertyType, lotAreaValue, address, imgSrc, price, bedrooms, longitude, latitude, listingStatus, zpid, listingSubType, contingentListingType, daysOnZillow, bathrooms, livingArea, country, currency, lotAreaUnit, hasImage’. If you intended to use one of these existing properties, you should replace tableName with the correct property name.

@concat(formatDateTime(addSeconds('1970-01-01T00:00:00Z', div(item().dateSold, 1000)), 'yyyy/MM'), '/', item().<correct_property_name>)
Replace <correct_property_name> with the actual property you want to use. If you still encounter issues this might require a deeper investigation from our engineering team about your workspace, and the logic behind it to properly understand what might be happening.
