Error rendering value of Live SQL Custom Field. Invocation of method 'getDatabaseRows' in class net

[ivancaceres20]

I created a Live SQL Custom Field, which worked without problems, but since 3 days ago, the following error started to appear in the main window of the issue.

An error occurred whilst rendering this message. Please contact the administrators, and inform them of this bug. Details: ------- org.apache.velocity.exception.MethodInvocationException: Invocation of method 'getDatabaseRows' in class net.bytesource.jira.database.DBConnection threw exception java.lang.AbstractMethodError at net.bytesource.jira.live-sql-custom-fields-plugin:live-sql-custom-fields//templates/customfields/my-field/view.vm[line 1, column 15] at org.apache.velocity.runtime.parser.node.ASTMethod.handleInvocationException(ASTMethod.java:351) at org.apache.velocity.runtime.parser.node.ASTMethod.execute(ASTMethod.java:284) at org.apache.velocity.runtime.parser.node.ASTReference.execute(ASTReference.java:262) at org.apache.velocity.runtime.parser.node.ASTReference.render(ASTReference.java:342) at org.apache.velocity.runtime.parser.node.SimpleNode.render(SimpleNode.java:336) at org.apache.velocity.Template.merge(Template.java:328) at org.apache.velocity.Template.merge(Template.java:235) at org.apache.velocity.app.VelocityEngine.mergeTemplate(VelocityEngine.java:381) at com.atlassian.velocity.DefaultVelocityManager.writeEncodedBodyImpl(DefaultVelocityManager.java:117) at com.atlassian.velocity.DefaultVelocityManager.writeEncodedBody(DefaultVelocityManager.java:97) at com.atlassian.jira.template.velocity.DefaultVelocityTemplatingEngine$DefaultRenderRequest.toWriterImpl(DefaultVelocityTemplatingEngine.java:122)
