If anyone make this issue before, help me resovel it, thank you so much

Hey,

You need to look at the custom.conf key in the serverless config.
The issue is in this fragment of the serverless.yml:

  conf: ${file(./${self:custom.confFile.${self:provider.stage}})}
  confFile:
    local: workers.conf.local.yml
    dev: workers.conf.yml
    qa: workers.conf.yml
    prod: workers.conf.yml

You are trying to build the saas environment and there is no confFile.saas key.
You need to add a single line and it should work:

  conf: ${file(./${self:custom.confFile.${self:provider.stage}})}
  confFile:
    local: workers.conf.local.yml
    dev: workers.conf.yml
    qa: workers.conf.yml
    prod: workers.conf.yml
    saas: workers.conf.yml
