Issue with campaign import from google ads

Hello all, I am having issue with campaign import via API. When i trigger my function to create job i receive such response: (reply){

ImportJobIds =

(ArrayOflong){

long[] =

12345,

}

PartialErrors = ""

}

but when i request job result i receive status = Failed and no further description or log, also on user interface I see created job, but failed with a message :"Internal error thrown from the application." and summary System error – can’t import right now.
