Use custom command / script to launch Conda environment

I made a small script ca.sh to activate a specific Conda environment so I don't have to repeatedly type out conda activate my_env. The script is executable and in a directory in the $PATH.

#!/bin/bash                    
                              
conda activate airbyte

When I run it, it gives the error

CondaError: Run 'conda init' before 'conda activate'

How do I get my script to activate the Conda environment in the current working directory? I'm running Ubuntu Linux.
