unexpectedly stopped working with - ERROR (Kamal::ConfigurationError): Secret 'KAMAL_REGISTRY_PASSWORD' not found in .kamal/secrets

[santy18]

App no longer builds with this error: ERROR (Kamal::ConfigurationError): Secret 'KAMAL_REGISTRY_PASSWORD' not found in .kamal/secrets

no changes have been made to any of the files. Now, the secrets file

# Grab the registry password from ENV
KAMAL_REGISTRY_PASSWORD=$KAMAL_REGISTRY_PASSWORD

# Improve security by using a password manager. Never check config/master.key into git!
RAILS_MASTER_KEY=$(cat config/master.key)

my .env has the env var

and I have tried both
kamal setup and dotenv kamal setup

To add, when I do kamal secrets print

the env var does not show up regarless of what value I put. I can put a string literal and nothing shows there

I have similar issues but my error does show the actual secrets i put in my env(from shell), making it more strange as it should be read in kamal.

  ERROR (Kamal::ConfigurationError): Secret 'xxxxxx' not found in .kamal/secrets

I have kamal v2.4.0.

after reading this thread I found dotenv kamal will work for me.
