Failed to read metadata error using File Upload > Upload a CSV

I’ve been attempting to insert data into InfluxDB Cloud Serverless via the web app’s File Upload > Upload a CSV functionality.

I am receiving an error “Failed to upload the selected CSV: error in csv.from(): failed to read metadata: default Table ID is not an integer” when uploading the following CSV data:

#group,FALSE,FALSE,FALSE,FALSE
#datatype,measurement,tag,double,dateTime:RFC3339
#default,weight,override,
measurement,source,qty,time

As best I can tell from reading the Annotated CSV documentation, this should work. I’m providing a table (measurement) name “weight” and getting an error about a missing integer Table ID.

Note that there is no data currently in the bucket for that measurement name, but I get the same error if I try to add the data to an existing measurement (table).

Any suggestions on how to get this to work would be greatly appreciated.
