I am getting the following exception while passing data as list to a step in step definition file as shown in the attached photo:

io.cucumber.core.exception.CucumberException: Could not convert arguments for step [^We are (\d+) adults$] defined at 'com.digitalpoint.cucumber.myHoliday.we_are(int,java.util.List<java.lang.String>)'.
It appears you did not register a data table type.

Caused by: io.cucumber.datatable.UndefinedDataTableTypeException: Can't convert DataTable to List<java.lang.String>.
Please review these problems:

- There was a table cell transformer for java.lang.String but the table was too wide to use it.
Please reduce the table width to use this converter.

- There was no table entry or table row transformer registered for java.lang.String.
Please consider registering a table entry or row transformer.

Note: Usually solving one is enough
