Fail to create Step Order about 3commas-official-api-docs

Probably, we didn't receive nested parameters. It all depends on how you send and encode parameters
Your data looks correct

I also tried it in Postman but still the same error.
Also, in the error response, the step number in take_profit[steps] changes every time.

Turn out that, I can sign the request with a JSON object instead of a query string. This fixes the problem.
