This policies also did not work in my rasa webchat application. I also deleted my pipeline. The following error I got :
(install_rasa) E:\New folder\Anaconda3\chat>rasa train YamlSyntaxException: Failed to read YAML. while parsing a block mapping in "<unicode string>", line 3, column 1: recipe: default.v1 ^ (line: 3) expected <block end>, but found '<block mapping start>' in "<unicode string>", line 34, column 3: policies: ^ (line: 34) You can use https://yamlchecker.com/ to validate the YAML syntax of your file.
