Mapbox Tiling Service errors

Public beta

Mapbox Tiling Service is in public beta. All features and workflows are subject to potential changes.

This guide outlines possible errors that you might see when creating, modifying, or deleting tileset sources, tilesets, and tileset recipes using Mapbox Tiling Service (MTS).

There are gaps of missing data in my tiles

If you notice that your tileset is missing points, lines, or polygons, it’s likely that MTS dropped some features because the tile size was approaching the maximum allowed size of 500 KB. If you view the job_id of this tileset, you will see warnings about how many tiles dropped features and a list of example tiles so you can diagnose the problem.

To avoid hitting the 500 KB limit, you should reduce the number and size of features. You can do this by:

  • Increasing the recipe simplification level.
  • Only allowing certain attributes to exist in the final tileset.
  • Unioning adjoining features, such as LineStrings, which reduces the number of features in the tiles.

My minzoom is different than expected

MTS tries to generate tiles for every requested zoom level. If the zoom levels in a tileset do not match the zoom levels in the corresponding recipe, this is due to features being filtered out based on the rules you have provided, which led to empty tiles at these zooms.

For example, if you specify a zoom level of 6 but your filtering syntax only starts accepting features at zoom 8, once processing is complete MTS will dynamically set the tileset's minzoom to 8 since there are no tiles to be requested at zoom 6 or 7.

There are "notches" in my LineStrings at high zooms

Notches in LineStrings happen when high zoom tiles do not have buffers that are large enough. To avoid possible buffer-edge artifacts, set your buffer_size to something larger than the default of 0.5. The recommended value is 6.

The features in my vector tiles have different IDs than the features in my source data

Vector tiles only support integer-based identifiers. If you provide an ID in the tileset source in any format other than integers, MTS will generate an integer hash of this value to use as the feature ID.

If you need to keep the original source IDs, you can do either of the following:

  • Use integer IDs in the source data.
  • Save the original ID of the feature as an attribute in the vector tiles using the set option in your recipe.

A feature I expected to be in my new tileset isn't there

If a feature that you expected to see is not in the new tileset, it might have been dropped for one of the following reasons:

  • The tileset source data was not valid GeoJSON. You can diagnose the problem by using the Tilesets CLI's validate-source command to validate your source data.
  • The feature was filtered out by your recipe. For more information on how and why a recipe might filter out a feature, see the Mapbox Tiling Service recipe reference.
  • The feature has been simplified away at certain zoom levels. For more information on feature simplification, see the Mapbox Tiling Service recipe reference.

I'm not able to use GeometryCollection features in my tileset source

Tileset sources do not support GeoJSON GeometryCollection features. If you have GeometryCollection features in your source data, you should split each of its sub-features into a unique, individual feature.

There are no features in my tileset when I click "zoom to data" in Mapbox Studio

Depending on how your data is distributed or the zoom range you choose, knowing where your data is can be a challenge. Mapbox Studio tries to help you visualize your data at the right location, but due to how it makes this calculation, you may not see any features if there are not any at the mathematical center of the tileset source used to create the tileset. If this occurs, you will need to manually click and drag the map to your feature locations, rather than being able to click "zoom to data".

A publish job failed

If a tileset publish job fails, you can find information about any errors by querying the Retrieve information about a single tileset job endpoint.

A common reason that a tileset publish job might fail is that the tileset contains too much data at too high of a max zoom. If your data does not need the level of precision offered by a higher max zoom, we recommend using a lower max zoom level, which may cause a failing job to succeed. Learn more about which max zoom level to use based on your data and use case.

Another reason that a tileset publish job might fail is because it is referencing a tileset source that was deleted while the tileset publish job was still processing. Make sure you don't delete a tileset source that is being used by a tileset with a processing status.

If a publish job fails, I want to retry it automatically

If a tileset publish job fails, you may be interested in retrying it automatically. To do this, set up your system so that it queries the Retrieve information about a single tileset job endpoint on a set interval. If the response object indicates stage: failed, your system should go through the publish process again for that tileset job.

Tilesets CLI error messages

The following is a list of common errors that you may see when using the Tilesets CLI, which allows you to interact with and prepare data for Mapbox Tiling Service.

No features in source data.

You may see this error after you run the Tilesets CLI command to publish a tileset.

The problem could be that your tileset source is an empty file, or that it does not contain any line-delimited GeoJSON features. Check the tileset source to confirm that it contains valid features.

No GeoJSON features processed. Make sure your GeoJSON is line-delimited.

You may see this error after you run the Tilesets CLI command to publish a tileset.

This error is most common when a tileset source is a GeoJSON file, but is not line-delimited GeoJSON. MTS requires all tileset sources to be line-delimited to process correctly. You can learn more about the line-delimited GeoJSON format and some conversion tools in the Tileset sources guide.

No GeoJSON features to process.

You may see this error after you run the Tilesets CLI command to create a tileset.

The problem may be that your data was not uploaded. Check that the data was indeed uploaded.

You may also see this error if the filter in your recipe is failing for some reason. If you have a filter condition like [ "<=", [ "get", "minzoom" ], 5 ], and one or more of your features has a null value for minzoom, you could run into this error. You can use the coalesce operation in an expression to provide a default value to replace missing data. For instance, if you want a missing minzoom attribute to be treated as 0, you could write this expression as [ "<=", [ "coalesce", [ "get", "minzoom" ], 0 ], 5 ]. For more information on recipe filters, see the Recipe reference.
