Limit order (buy) fails

[LaoTszy]

Limit order (buy), e.g:

await tr.limit_order(order_id, 'DE0007037129', 'buy', '1', '21.78', 'gfd')

fails with

Unrecognized state E data ['{"errors":[{"errorCode":"JSON_PARSE_ERROR","errorField":null,"errorMessage":"Subscription', 'payload', '<{\"type\":\"simpleCreateOrder\",\"clientProcessId\":\" < some generated uuid > \",\"warningsShown\":[\"userExperience\"],\"acceptedWarnings\":[\"userExperience\"],\"parameters\":{\"instrumentId\":\"DE0007037129\",\"exchangeId\":\"LSX\",\"expiry\":{\"type\":\"gfd\"},\"limit\":\"21.78\",\"mode\":\"limit\",\"size\":\"1\",\"type\":\"buy\"},\"token\":\" < the very long token > \"}>', 'validation', 'failed","meta":{"source":"MAPPER"}}]}']

This json above really looks funny with "errorMessage" value looking like a fragment of the payload without its head and tail parts.

HMMM, is this maybe related to #21 which I merged yesterday?

[Zarathustra2]

What if you use the previous commit before the merge?

[LaoTszy]

I have indeed used the version preceding the merge. The error looks a bit different now with an exception thrown in TRApi.start. The content of the message is still the same though:

Traceback (most recent call last):
File "using_tr.py", line 25, in history
await tr.start()
File "api.py", line 349, in start
raise TRapiExcServerErrorState(f"Error during server access\n\tServer-side Object probably expired...\n\t{sErr}")
trapi.api.TRapiExcServerErrorState: Error during server access
Server-side Object probably expired...
ERROR state: E data: ['{"errors":[{"errorCode":"JSON_PARSE_ERROR","errorField":null,"errorMessage":"Subscription', 'payload', '<{\"type\":\"simpleCreateOrder\",\"clientProcessId\":\" \",\"warningsShown\":[\"userExperience\"],\"acceptedWarnings\":[\"userExperience\"],\"parameters\":{\"instrumentId\":\"DE0007037129\",\"exchangeId\":\"LSX\",\"expiry\":{\"type\":\"gfd\"},\"limit\":\"35.85\",\"mode\":\"limit\",\"size\":\"1\",\"type\":\"buy\"},\"token\":\" \"}>', 'validation', 'failed","meta":{"source":"MAPPER"}}]}']

hmmm interesting. Not sure if I find the time to debug it as I don't use TR really

How did you come up with this API? I've tried to look at the the web application network exchange: it looks pretty different to me.

[Jeffote]

is there an update to this issue?

[deepbeat]

hello there, having the same issue. Anyone working on this? And if not, how and with what tools did you reverse engineer this API exactly?

[deepbeat]

Solved it. It still works with the given code. You just need to give a well-formated uuid as id. Otherwise you get this misleading JSON_PARSE_ERROR from above.

However, I am still very interested in this open question: how and with what tools did you reverse engineer this API exactly?
