I get the following exceptions in the Jenkins log after 2.X upgrade, I have already changed target to selectedTarget in groovy but still getting the following:

java.lang.UnsupportedOperationException: no known implementation of class java.lang.String is named Targetjava.lang.UnsupportedOperationException: no known implementation of class java.lang.String is named Target at org.jenkinsci.plugins.structs.describable.DescribableModel.resolveClass(DescribableModel.java:549) at org.jenkinsci.plugins.structs.describable.UninstantiatedDescribable.instantiate(UninstantiatedDescribable.java:207) at org.jenkinsci.plugins.structs.describable.DescribableModel.coerce(DescribableModel.java:466) at org.jenkinsci.plugins.structs.describable.DescribableModel.buildArguments(DescribableModel.java:409) at org.jenkinsci.plugins.structs.describable.DescribableModel.instantiate(DescribableModel.java:329)

Currently running the plugin version 2.5 - here is the xml configuration of the /jenkinsci.plugins.influxdb.InfluxDbGlobalConfig.xml file attached as a screenshot.

The exceptions are flooding the log file causing it to be un-readable.
