Insufficient funds when fetching bitcoin data

My own counterparty node are fetching data. but i got this error

INFO:blockfeed: Block: 539130 of 539130 [message height=4987622]
ERROR:manager: API Exception: {‘type’: ‘Exception’, ‘message’: ‘{“code”: -32001, “message”: “Error composing order transaction via API: insufficient funds”}’, ‘args’: (‘{“code”: -32001, “message”: “Error composing order transaction via API: insufficient funds”}’,)}
Traceback (most recent call last):

result = method(*request.args, **request.kwargs)
File “/counterblock/counterblock/lib/processor/api.py”, line 371, in proxy_to_counterpartyd
raise Exception(errorMsg if errorMsg is not None else “UNKNOWN”)

I often get insufficient funds error when i dont have enough amount to create_send or create_order. But this is just fetch bitcoin data only. why do i get this error ?!

Thanks
