Position gets opened according to logs but not in reality

[zakski2]

Hello,
I'm writing simple script to use signals according to which the script should place an order via FIX API to my broker account. I use ICMarkets demo account to run my tests. I wrote it in Python and used ejtraderCT to communicate with API
So far my script outputs in logs that everything works just fine - it tells that it connects to FIX, logs in my account, parses my signals and finds them, then places an order and receives something like a ticket and closes.
Problem is that in fact it does nothing. No orders in my demo account (which I see in cTrader web). And if believing cTrader active sessions page, no additional logons happen
My question is how to change this? I can see in other issues and similar questions that code similar to mine works just fine. What I'm doing wrong?

Here's the output in my logs:

It tells at the end of the log that no positions were found (I used api.positions() to output that). At the same time, it just wrote above that it kinda opened something (in fact it didn't, api.positions doesn't lie)
I tried to ask in the broker support, they told to go elsewhere for help and that they don't provide support for API.
Where to search for problem?

Right, now that I just opened an issue, I found the problem
Reason was in how I was opening (or trying to open) the position. I wrote:
pos_id = api.buy(XAU_SYMBOL_NAME, volume, sl, tp) if side == 'buy' else api.sell(XAU_SYMBOL_ID, volume, sl, tp)
... Trying to solve 2 tasks with one line, I guess, which is to make it get instantly direction of the order I want to place. And this didn't work. What it did was how in my output above, while no orders were in fact opened.
All it did was just silently eating that error without actually telling anything that it fails to place the order or something
If commenting it out before "if", it places buy order fine, i.e my code logic was wrong
So I needed to search for the problem in my code

UPD. Just to make my findings a bit clearer, I see that orders won't be placed if I use symbol name in the order opening process, i.e writing
api.buy(SYMBOL_ID, ....)
...will not make anything work.
If I write api.buy(SYMBOL_NAME, ...), I get the position opened just fine
