Error message "Field delimiter '\t' found while expecting record delimiter '\n'" in API - using method GET

[Phuong Thao]

Hi guys,
I have a question from my client about an issue regarding the error message related to using the method "GET" in API service-now.
Questions from the client:
Currently, we saw some ‘extra space’ (Special Character) in the "Anonymous Name" field - This field get from a catalog item.
Need to answer for the client:
1. We would like to understand why our API is causing issues in fetching the Data [if any ‘extra space’ or Special Character exists].
2. Is it possible to correct and share the APIs to support such odd cases if exist.

Error message screen-shot:








Please help me resolve this issue. Thank guys so much!

Hi,

Did you check that field has some data/text which is not a valid character?

Hi Ankur,

Yes, I think they checked.
They use the ServiceNow Developers shared APIs to fetch the data then they saw the issue [extra space], after deleting Special Character [extra space], It's working fine, data is captured successfully. 
But they don't know the reason why it has an issue exists. So they need to us explain that reason.

Best regards,

Hi,

how does the data in field look like in UI?

can you share that?

what endpoint they are using? what response they are expecting and what space is shown?

Hi Ankur,

Sorry, I can't. I also request the client provide evidence [ex: screenshot,..]. But they just shared only an error message for us.

Thank you for your response!!!
