Azure data factory - bob delimited data set error on parameterizing row delimiter

Question

Hi
We have created a dataset that is used to write blob to our storage container. Out idea was to parameterize ceratin connection properties like FilePath, column delimiter, row delimiter and encoding - so team members can generate client data files using different delimiters(comma, pipe) or encoding(UTF-8 or 16) or row delimiter(like \r, \n or \r\n).

All parameters except the row delimiter work. When we try to pass \r\n for the row delimiter parameter value we get an error

Operation on target Get Veeva Data failed: ErrorCode=DelimitedTextInvalidSettings,'Type=Microsoft.DataTransfer.Common.Shared.HybridDeliveryException,Message=Copy activity doesn't support multi-char or none row delimiter.,Source=Microsoft.DataTransfer.ClientLibrary

When we change the row delimiter to Default setting it works fine. Any way this can be achieved.

Hello @Siddharth Kumar ,
Thanks for the question and using MS Q&A platform.

As I understand the ask is how to use for a row delimiter, the combination \r\n when the row delimiter is parameterized in dataset.

There is a layer of nuance in the explanation why typing "\r\n" does not work. This takes the actual 4 characters [\,r,\,n] instead of the 2 escaped characters they represent. Furthermore, pressing enter in the textbox doesn't enter the desired value.

However I found that when I open the expression editor, and press enter or paste in the actual carriage return + newline (as opposed to "\r\n") , the validation error goes away.

I know its kinda confusing, but it is like "two" vs "2". While both represent a quantity, one is a word while the other is a digit.

Please do let me if you have any queries.

Thanks
Martin
