Validation error - Invalid Regular Expression

[FreshRob]

I am using the same slug regex as Compose and I am able to use it in the contentful UI however the migration is rejecting it.

^((\/)|(([\/\w\-\._~:!$&'\(\)*+,;@]|(%\d+))+))$

Expected Behavior

Accept regex and create contentType

Actual Behavior

 Error: {"status":"Unprocessable Entity","message":"Validation error","details":{"errors":[{"name":"type","type":"Validation","value":{"regexp":{"pattern":"^((/)|(([/w-._~:!$&'()*+,;@]|(%d+))+))$"}},"details":"Invalid regular expression","path":["fields",1,"validations",0]}]},"url":"spaces/*****/environments/master/content_types/Article"}

Steps to Reproduce

  contentType
  .createField("slug")
  .name("Slug")
  .type("Symbol")
  .required(true)
  .validations([{ regexp: { pattern: "^((\/)|(([\/\w\-\._~:!$&'\(\)*+,;@]|(%\d+))+))$"  } }]);

I'm running in to this same version on 1.10.0 of the Contentful CLI

For anyone in the future reading this, I had this error too and fixed it:

slug_validation = Contentful::Management::Validation.new
slug_validation.regexp = {
  pattern: %r{^((\/)|(([\/\w\-\._~:!$&'\(\)*+,;@]|(%\d+))+))$}.inspect.gsub(%r{^/|/$}, '')
}
slug_validation.message = "That doesn't look like a valid slug"

namely by adding .inspect.gsub(%r{^/|/$}, '') got it to work for me, you can see below the difference namely with escape characters:

p = %r{^((\/)|(([\/\w\-\._~:!$&'\(\)*+,;@]|(%\d+))+))$}

p.inspect 
=> "/^((\\/)|(([\\/\\w\\-\\._~:!$&'\\(\\)*+,;@]|(%\\d+))+))$/"

p.inspect.gsub(%r{^/|/$}, '')
=> "^((\\/)|(([\\/\\w\\-\\._~:!$&'\\(\\)*+,;@]|(%\\d+))+))$"
