No Map Layer named LookML Warning

Looker Q&A Looker

Hi,

I have defined a map_layer_name following all these steps

My map works perfectly in development mode and I can see my data plotted as I would expect it.

However, when Validating LookML it says that my map layer is not defined

I have tried exiting the developer mode and developing again, using another browser I have never used for developing, changing the name of the map layer and still no success. Any idea why this could be happening?

How do I bypass a warning if it’s actually working?

thanks!

Hi Luciana!

Could you share the map_layer definition? Perhaps one parameter is missing

map_layer: identifier {
  extents_json_url: "string"
  feature_key: "string"
  file: "/file_path/file_name.json" # or use the url subparameter
  format: topojson | vector_tile_region
  label: "string"
  max_zoom_level: number
  min_zoom_level: number
  projection: airy  # or one of many other choices
  property_key: "string"
  property_label_key: "string"
  url: "string" # or use the file subparameter
}

Maps parameters

Hope it helps!

Best,

Leo

Hi Leo,

thanks for answering.

From the guidelines I interpreted that all the default values would map my file, so I have not configured any extra ones. I have this at the moment and it’s still giving errors.

And as said, it’s working when I do an explore with it.

Any ideas?

thanks!!!

I discovered the mistake!!!

the error was not coming from the map_layer, bu the map layer not being defined in every single model we use the view. We have many views that we join all over and therefore the map_layer needs to be declared in each of those models so that it can be taken.

I wish this could be done from the manifest, but apparently is not possible.

Hi Luciana!

I agree. There is a post of Daniel Mintz ( A Hero without a cape haha) which covers one example using manifest file to reuse a json variable and use it in map layers, perhaps it will help :

Thanks Leo, I came across that post before, but I didn’t want to use a public tool to access the maps as the definition of our focus regions is strategical information.

But I will have a look.

Thanks for the help!
