Git pull always shows error "Permission denied (publickey). fatal: Could not read from remote repos"

[Arjun Thakur]

I was already configure the ssh key in my bitbucket access key location.
I am using atlassian/ssh-run:0.4.0 module for ssh it is working fine but when my bash script command runs then git pull shows error "

Permission denied (publickey).
fatal: Could not read from remote repository.
Please make sure you have the correct access rights"
this is my bash script code :-

#!/bin/bash

if [[ "$BRANCH" == "featurecicd" ]]; then
echo 'Aborting script';
cd /usr/share/nginx/html/........../.../.../../
pwd
sudo git stash

repos=(
"featurecicd"
)
echo ""
echo "Getting latest for" ${#repos[@]} "repositories using pull"

for repo in "${repos[@]}"
do
echo ""
echo "****** Getting latest for" ${repo} "******"
cd "${repo}"
sudo git pull
echo "******************************************"
done

#sudo git pull
sudo git stash pop
npm i
npm run build

when I runs these command in my server manually it not show any error
my git remote already added ssh type

plz
