I am running a Data Lake - Analytics job and I getting the below error

ERROR VertexFailedFast. Vertex failure triggered quick job abort. Vertex failed: SV1_Extract[0][0] with error: Vertex user code error. DESCRIPTION Vertex failed with a fail-fast error

Does anybody know why this happens?

You cut off the error message part that actually tells why your extraction failed.

If you use a built-in extractor, it may be because you fail a data type cast, you have incorrect numbers of columns (for a variety of reasons) etc.

If you use a user defined extractor, it could be because of any C# runtime error that the user code generates.
