System error code: 1019

I try to load Mturk hits for our account.
I use boto3 and ListHits function. After I download ~ 55 days. I start receiving just error System error code: 1019 .
I restart process and it failed on the same date. What does it mean ? How I can overcome this problem ? Is this is some limitation for this function / API ?

hello

here is my code

Note: I receiving the same problem with aws cli too . I'm not sure that problem with code because :

• it load's data during 2 days, and then start failing on specific historical dates (I repeat it 2 times and behaviour the same . It load's data from now to middle of the March and then start failing )
• I picked nextToken and got same issue with was cli
• I continued tries and after 1 day it worked some time and downloaded ~ 1 week of data.
• Now it stop working and token expired.
• And for getting this error I need to parse our data again during next week what is annoying.

AWS CLI USAGE:

aws mturk list-hits --max-items=100 --page-size=100 --starting-token=p2:d*******O

An error occurred (ServiceFault) when calling the ListHITs operation (reached max retries: 2): There was an error with this request. (System error code: 1019 1653038262906)
