What is MySQL error 3070 ER_INVALID_GEOJSON_MISSING_MEMBER?

ER_INVALID_GEOJSON_MISSING_MEMBER appears when a MySQL spatial function receives GeoJSON missing a required member. Verify that type and coordinates (or geometries) exist and are correctly spelled to fix the error.

Explanation

Table of Contents

What does ER_INVALID_GEOJSON_MISSING_MEMBER mean?

MySQL throws error 3070 when a spatial routine such as ST_GeomFromGeoJSON or ST_PointFromGeoJSON receives input that is not fully compliant with the GeoJSON specification. The parser stops as soon as it detects that a compulsory member is absent.

When does MySQL raise this error?

The error occurs during runtime evaluation of functions that convert or validate GeoJSON. It is version specific: MySQL 5.7.5 and later added server side checks that trigger 3070 before generating a geometry object.

Why is it critical to fix?

A failed GeoJSON conversion returns NULL, halts spatial queries, and may cascade to application timeouts. Ensuring valid GeoJSON keeps spatial indexes usable and guarantees accurate query results.

What Causes This Error?

An input string missing the type key, coordinates array, or geometries array causes immediate failure. Typos such as Type or coordinate also trigger the exception.

How to Fix ER_INVALID_GEOJSON_MISSING_MEMBER

Validate the JSON before calling ST_GeomFromGeoJSON, ensure all mandatory members are present, and correct any spelling or case sensitivity errors.

Common Scenarios and Solutions

APIs sometimes send partial GeoJSON. Adding middleware validation prevents bad payloads from reaching the database.

Best Practices to Avoid This Error

Use CHECK constraints or INSERT triggers to reject malformed data at write time. Adopt schema aware SQL editors like Galaxy to surface issues early.

Related Errors and Solutions

Errors 3060, 3037, and 1416 also arise during spatial processing. Their fixes follow similar validation steps.

Common Causes

Missing type member

The input object omits the required type key, so the parser cannot infer geometry kind.

Missing coordinates array

Point, LineString, and Polygon objects need a coordinates member; without it, MySQL raises error 3070.

Missing geometries array

GeometryCollection objects must contain geometries; omitting it triggers the exception.

Case sensitivity mistakes

Using Type or Coordinates rather than the exact lowercase names causes validation failure.

Related Errors

ER_INVALID_GEOJSON_TOO_FEW_POINTS

Raised when LineString has fewer than two points.

ER_GIS_INVALID_DATA

Occurs when binary or textual spatial data cannot be parsed.

ER_DATA_OUT_OF_RANGE

Triggers when coordinate values fall outside valid latitude or longitude limits.

FAQs

Does MySQL automatically fix malformed GeoJSON?

No. The server rejects invalid documents instead of correcting them.

Is error 3070 affected by SQL_MODE?

The error is independent of SQL_MODE; validation happens inside spatial functions.

Can I bypass validation?

No safe method exists; you must supply valid GeoJSON.
