In my pipeline configuration i trying connect in a EC2 service, im have a variable calls SSH_KEY in bitbucket , im trying to take a .pem value in, but in my pipeline when i try convert the variable to .pem file and connect in EC2 instance , i receive the error: Load key "conder-key-dev.pem": error in libcrypto
and Permission denied (publickey)., but if i write the .pem value exposed in the code , i can connect normally, how should i write this .pem value in the variable in the bitbucket?
