   Yes @mgubaidullin you can find out via camel-catalog model files, eg
   
   In camelYamlDsl.json you have
   
   ```
         "org.apache.camel.model.RouteDefinition" : {
           "type" : "object",
           "properties" : {
             "autoStartup" : {
               "type" : "boolean"
             },
   ```
   
   Then you can find out its an option on `org.apache.camel.model.RouteDefinition`, which you can find in camel-catalog and match by `javaType` as in `route.json` snippet below:
   
   ```
   {
     "model": {
       "kind": "model",
       "name": "route",
       "title": "Route",
       "description": "A Camel route",
       "deprecated": false,
       "label": "configuration",
       "javaType": "org.apache.camel.model.RouteDefinition",
   ```
   
   Then you have the correct model class, and inside its properties you can find
   
   ```
       "autoStartup": { "kind": "attribute", "displayName": "Auto Startup", "required": false, "type": "string", "javaType": "java.lang.String", "deprecated": false, "autowired": false, "secret": false, "defaultValue": "true", "description": "Whether to auto start this route" },
   ```
   
   And see that the type is `string`. And therefore it supports what the user reported.
   
   I assume you use this kind of "indirection" anyway to find documentation (eg = description) for every EIP option. So karavan must have some code that captures this, and then you can use it to find out which options can also be a "string" where you can use property placeholders, env variables and so on.
   
   This can also happens for options that are numeric (not only for boolean)
