I've encountered an exception when starting a new stack :

Whitelabel Error Page

This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Bad Request, status=400).
Failed to convert value of type 'java.lang.String' to required type 'io.codeka.gaia.stacks.bo.JobType'; nested exception is org.springframework.core.convert.ConversionFailedException: Failed to convert from type [java.lang.String] to type [@org.springframework.web.bind.annotation.PathVariable io.codeka.gaia.stacks.bo.JobType] for value 'apply'; nested exception is java.lang.IllegalArgumentException: No enum constant io.codeka.gaia.stacks.bo.JobType.apply
org.springframework.web.method.annotation.MethodArgumentTypeMismatchException: Failed to convert value of type 'java.lang.String' to required type 'io.codeka.gaia.stacks.bo.JobType'; nested exception is org.springframework.core.convert.ConversionFailedException: Failed to convert from type [java.lang.String] to type [@org.springframework.web.bind.annotation.PathVariable io.codeka.gaia.stacks.bo.JobType] for value 'apply'; nested exception is java.lang.IllegalArgumentException: No enum constant io.codeka.gaia.stacks.bo.JobType.apply

Maybe we should also duplicate the 500 error page to the 400 :)

I believe the error comes from here :

new_stack.js line222

function run(){
    // save the stack & run job
    $.ajax({
        url: `/api/stacks`,
        data: JSON.stringify(this.stack),
        contentType: "application/json",
        method: "POST"
    }).then(saved => {
        this.stack = saved;
        window.location = `/stacks/${this.stack.id}/apply`;
    })
}
