Describe the bug

After we successfully build again the backend-api from staging/development branch, it kept on failing with errors that seem related to dexalot connector

                                                                                             ✔  1m 38s

Steps to reproduce bug

  1. For hummingbot, first clone the hummingbot using the staging/development branch
    • Build local .whl and copy the dir from ./dist/your_local.whl backend-api's environment.yml
  2. On Backend-api, run make install && make run
  3. Observed after 1-2mins and error will occur

Tried to copy dexalot.yml file see if this fixed the issue but nogo, getting same error causing backend-api to not start and sync with dashboard and broker image
