sls print is including deprecation text

Yes, version 2.16.0

I’m using “sls print” within a bash script to resolve variables. This is read from YAML format, and piped to a an output file which is also expected to contain YAML. The deprecation text is also written out, which renders it invalid YAML when trying to parse/query with yq library.

Apologies, I cannot include the full configuration. Regardless - there is nothing special to this issue; it simply requires a version of serverless for which “sls print” includes the deprecation text as output, and a script using yq to read any arbitrary property from it.

sls print
–stage ${SLS_STAGE}
–region ${AWS_REGION} \

/tmp/serverless.yml

⚠️⚠️ REPLACE WITH FULL COMMAND OUTPUT

The env variable worked. Thank you for that! Specifically, I used in my bash startup script:

export SLS_DEPRECATION_DISABLE=*

Hello @thetumper, thanks for reporting back. As for using the variable, I believe you should still be able to prepend your command with SLS_DEPRECATION_DISABLE, e.g. SLS_DEPRECATION_DISABLE='*' sls print.

What is the full list of deprecation codes?

Unfortunately, we don’t have the codes listed anywhere in the documentation, but I’ve just opened an issue that aims to improve existing deprecation documentation: https://github.com/serverless/serverless/issues/8665

As for not including warnings in print command, we have a plan for a bigger refactoring/improvement of our logging mechanisms: https://github.com/serverless/serverless/issues/1720 which we will be prioritizing in the near future. That should resolve issue with print as well.
