How to escape $ sign in serverless yaml config?

amazon-web-services, aws-api-gateway, serverless-framework, yaml

Solution

As author said, customizing variableSyntax worked for me:

  # notice the double quotes for yaml to ignore the escape characters!
  # Use this for allowing CloudFormation Pseudo-Parameters in your serverless.yml
  # e.g. ${stageVariables.my_var}. All other Serverless variables work as usual.
  variableSyntax: "\\${((?!stageVariables)[ ~:a-zA-Z0-9._@'\",\\-\\/\\(\\)]+?)}"

Problem

I want to escape $ sign when using stage variables for api gateway. Following error appears when I try to deploy. Invalid variable reference syntax for variable stageVariables.capabilitySecurityUrl. You can only reference env vars, options, & files. You can check our docs for more info. I have tried following options, but not working 1) Using Without Quotes Uri: https://${stageVariables.capabilitySecurityUrl} 2) Using with quotes Uri: "https://${stageVariables.capabilitySecurityUrl}" 3) Access variable from file ``` ./stageVariables.json { "capabilitySecurityUrl":"https://${stageVariables.capabilitySecurityUrl}" } ./serverless.yml ${file(./stageVariables.json):capabilitySecurityUrl} ``` Any help?
