Symptoms

Bamboo fails to start. This error is written in the logs:

Elastic Bamboo Error : Null value was assigned to a property of primitive type setter of com.atlassian.bamboo.agent.elastic.server.ElasticImageConfigurationImpl.legacyEbsHandlingEnabled; nested exception is org.hibernate.PropertyAccessException: Null value was assigned to a property of primitive type setter of com.atlassian.bamboo.agent.elastic.server.ElasticImageConfigurationImpl.legacyEbsHandlingEnabled

Cause

The root cause of this issue is that the ELASTIC_IMAGE  table has a column LEGACY_EBS_HANDLING which can only accept an integer value. If that column has a null value, Bamboo complains and fails with the error above. You can check this by running the command below:

SELECT * FROM elastic_image WHERE legacy_ebs_handling IS NULL;

Resolution

1. Shutdown Bamboo;
2. Backup the database, for safety;

3. Run the query below:

   UPDATE elastic_image SET legacy_ebs_handling = 0 WHERE legacy_ebs_handling IS NULL;

4. Start Bamboo.
