Error while installing project with docker image unable to load fixture

Getting the error when loading fixture

** Loading fixtures into database **
Traceback (most recent call last):
  File "/usr/local/lib/python3.5/dist-packages/django/db/backends/utils.py", line 62, in execute
    return self.cursor.execute(sql)

The above exception was the direct cause of the following exception:

@SameerRathod Thank you for reporting this issue. My guess, this could be caused due to the recent migrations.
We will investigate and send in a fix as soon as possible.

In the meantime you can clone the project cd to the project directory and manually run the Django server,

python manage.py migrate
python manage.py runserver

and manually run the Code Server (used to evaluate programming questions) in a new terminal,

cd ./code_server
python3 -m code_server.py

@ankitjavalkar
I resolved it. I was skipping the .env file step while creating docker. I found out by default it is taking SQlite as DB. I pointed it to MySql and it worked.
Thank you 😊
