Exception after submitting an order

[BrelKsiba]

I have a loop in which I am checking some conditions. Once these conditions verified, I am submitting an order.

Very few times where the submit function is called without an error but most of the time I have the following exception.

result = client.submit(transaction_group1, wait=True)
File "D:\Programs\lib\site-packages\tinyman\v1\client.py", line 34, in submit
raise Exception(json.loads(e.args[0])['message']) from None
File "D:\Programs\lib\json_init_.py", line 346, in loads
return _default_decoder.decode(s)
File "D:\Programs\lib\json\decoder.py", line 337, in decode
obj, end = self.raw_decode(s, idx=_w(s, 0).end())
File "D:\Programs\lib\json\decoder.py", line 355, in raw_decode
raise JSONDecodeError("Expecting value", s, err.value) from None
json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)

Any idea about the root cause of this non deterministic behavior resulting to this exception?
Many Thanks

It would be very helpful if you could modify D:\Programs\lib\site-packages\tinyman\v1\client.py", line 34, to print e and e.args so we can understand what is being returned in this case.
We assumed it was always some JSON but it seems this is not the case.

after adding print (e) and print (e.args) as suggested, I get the following:

TransactionPool.Remember: transaction ETIWFPB5AI3V4XI6VZGTADCQ4ZIUEDTPWA74PK7SVQY3JJOTFUWA: underflow on subtracting 6122893675 from sender amount 522767870
('TransactionPool.Remember: transaction ETIWFPB5AI3V4XI6VZGTADCQ4ZIUEDTPWA74PK7SVQY3JJOTFUWA: underflow on subtracting 6122893675 from sender amount 522767870',)

looks like related to numbers after decimals in the amount_in. may be I have to round it?
