I’ve setup a smart field that I’d like to be used to display a map widget. I’ve got the field returning the lat/long in the correct format but when I press Save on the Forest Dashboard I get an error.

## Expected behavior

Smart field is updated to show a Map widget

## Actual behavior

```javascript
venues update failed: Not-supported patch: {op:'replace',path:'/collections/venues/layout/fields/lat/long/widgetEdit'}

```

## Failure Logs

Please include any relevant log snippets, if necessary.

## Context

Please provide any relevant information about your setup.

- Express Version: ~4.16.3
- Sequelize Version: ^6.3.8

Hi @forestdan 👋 welcome to our community.  
I see your smart field name is `lat/long` and it’s not supported!  
Can you try with `lat-long` or `latlong`?  
If you absolutely want to name your field like this you could set the display name like that.
