I am trying to run my first Azure Streaming Analytics query:

User's image

But when I test the query I get the message "There is no data from input 'referencedata'. Please make sure the input source has data and then try again."

The reference dataset is in an ADLS Gen 2 account.

My reference dataset details:

User's image

The storage location:

User's image

The data:

User's image

Please advise.

    Hi thank you for posting this, I am running into exactly same situation now, any idea how did you resolved this back then? my file path is {date}/{time}/TMS.json, I also tried directly use TMS.json, but neither worked out. Once the start the job, nothing made to my destination. Any insight would be appreciated. Thanks!

    Hello James,

    I see you are using a Blob storage with the year/month/day path format.

    In the past, I also worked with reference data and I used the Time field too.

    Can you add an extra level to the path for the hour? The sub path '00' will do already.

    You need to change the path pattern too.
