Solved Missing Fields Microsoft Fabric Community This can result in columns being missing in the dataflow, even though they are present in the source data source. i hope this information is helpful. please do let us know if you have any questions. In microsoft fabric, when you load data into a lakehouse, you’re writing files to delta tables in onelake. however, the sql analytics endpoint—which provides the warehouse like querying capability—doesn’t immediately “see” these new files.
Solved Missing Fields In Visual Microsoft Fabric Community The fix? implement a forced metadata refresh before loading lakehouse bronze tables into the warehouse silver and gold layers. let me walk you through the technical details of what’s happening and how we solved it. the technical deep dive: understanding metadata refresh delays in microsoft fabric. The problem i have is that the json structure is sometimes missing fields which are records (nested objects) and all the many varied fixes workarounds i've tried (like selectfields or list.transform) work well if a regular field is missing but not if the missing field is a record type. When i open the dataflow the columns are there, when i publish and refresh the dataflow it refreshes everything in the lakehouse but the date columns. i assume it's something of a mapping issue, but i can't change this. Copy activity works well when the schema is consistent, but it can fail when nested fields are optional or missing in some responses. in this case, using a notebook or dataflow gen2 may help, since you can handle the json more flexibly and set null or default values when fields are not present.

When i look at the data source fields, i can see that "categories" are there. even when i initially connect to the data source, it shows as a "list" type field, but i dont see it as an available field in powerbi.
