How It Affects Your App
MySQL 1252 ER_SPATIAL_CANT_HAVE_NULL is an error that occurs when a spatial column is defined as NOT NULL but contains NULL values. This error can have a significant impact on an application as it can prevent the application from running properly.

Additionally, it can cause unexpected behavior in the application, such as incorrect results or unexpected errors.
How To Fix
1. Check the character set of the database:SELECT default_character_set_name FROM information_schema.SCHEMATA S WHERE schema_name = "database_name";
2. Change the character set of the database:ALTER DATABASE database_name CHARACTER SET = utf8mb4 COLLATE = utf8mb4_unicode_ci;
3. Check the character set of the tables:SELECT CCSA.character_set_name FROM information_schema.`TABLES` T, information_schema.`COLLATION_CHARACTER_SET_APPLICABILITY` CCSA WHERE CCSA.collation_name = T.table_collation AND T.table_schema = "database_name" AND T.table_name = "table_name";
4. Change the character set of the tables:ALTER TABLE table_name CONVERT TO CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;
5. Check the character set of the columns:SELECT character_set_name FROM information_schema.`COLUMNS` WHERE table_schema = "database_name" AND table_name = "table_name" AND column_name = "column_name";
6. Change the character set of the columns:ALTER TABLE table_name CHANGE column_name column_name VARCHAR(191) CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;
7. Use an automated database observability tool to monitor and fix the MySQL 1252 in question.
