activating conda environment in within a shell script

I have an EC2 instance running Ubuntu 18.04. I have a python Flask server implemented inside it, and I want it to start running as soon as I boot. I would like to do this with /etc/.

When I login and run the following in order, the conda environment activates, and therefore my Flask server runs well.

cd ~
cd pult
conda activate pult
export FLASK_APP=hello.py
flask run

So this is what I wrote in /etc/rc.local. The file did not exist, so I made one.

#!/bin/bash
cd ~
cd pult
sudo ln -s /home/ubuntu/anaconda3/etc/profile.d/conda.sh /etc/profile.d/conda.sh
conda activate pult
export FLASK_APP=hello.py
flask run

And when I run /bin/bash /etc/rc.local I get this error, and the conda environment fails to activate.

CommandNotFoundError: Your shell has not been properly configured to use 'conda activate'.
If your shell is Bash or a Bourne variant, enable conda for the current user with $ echo ". /home/ubuntu/anaconda3/etc/profile.d/conda.sh" >> ~/.bashrc
or, for all users, enable conda with $ sudo ln -s /home/ubuntu/anaconda3/etc/profile.d/conda.sh /etc/profile.d/conda.sh
The options above will permanently enable the 'conda' command, but they do NOT
put conda's base (root) environment on PATH. To do so, run $ conda activate
in your terminal, or to put the base environment on PATH permanently, run $ echo "conda activate" >> ~/.bashrc
Previous to conda 4.4, the recommended way to activate conda was to modify PATH in
your ~/.bashrc file. You should manually remove the line that looks like export PATH="/home/ubuntu/anaconda3/bin:$PATH"
^^^ The above line should NO LONGER be in your ~/.bashrc file! ^^^

I also tried:

• putting source ~/.bashrc in line 2 (running this should put conda in PATH)
• putting export PATH="/home/ubuntu/anaconda3/bin:$PATH" in place of line 4

But they all give the same error. What should I do, so that /bin/bash /etc/rc.local will activate the conda environment?
