Service Not Available (error code 21)

I am making queries to get inventory changes for around 2000 products. Sometimes I get Server Error 50x, but I can deal with that.

Now I am getting error SERVER NOT AVAILABLE: CODE 21.

Exception: {'message': 'Service not available', 'operation': 'inventory_changes', 'field': 'data', 'request_id': '5e74ac0b8234634de37cae0c', 'code': 21}

is there a reason or a solution for that ?

Thanks

Hi @khanhnc46!
I apologize for the delay in my response. Is this a recurrent issue?
I can’t seem to reproduce that behavior with your exact same query.
Any advice welcome!
Thanks in advance,
Tom.
