Dataflow: Validation of the model failed

Hi All


I was wondering if someone could help me with a Dataflow error I am getting. I have been struggling with it for the last 2 days and I am unable to find where the problem is to correct it.


The validation of the model failed. Error: 'Name length of 'Attribute' is incorrect. Name length: '0'. Minimum allowed length: '1'. Maximum allowed length: '256''



Not applicable

Hi andrew,


Same problem i have faced, check your table contains may be one a column/Attribute having no name or empty, provide column header and problem is solved..


All the best..

Hi. Can you tell us a bit more about the table, columns and data that is showing that error?


It looks like Attribute column has a text with more than 256 characters.
