Build failed with UnrecognizedPropertyException: Unrecognized field error

In my JSON file I have defined customMetrics as

"customMetricHeadings": [
  {
    "headingName": "CUSTOM VIEWABILITY",
    "customMetricCategory": "CUSTOM_VIEWABILITY"
  },
  {
    "headingName": "CUSTOM VIEWABILITY QI",
    "customMetricCategory": "CUSTOM_VIEWABILITY_QI"
  }
]

I have defined this customMetricCategory for different metrics in the same JSON file as

{
  "columnName": "nonQualifiedForViewabilityAds4",
  "columnLabel": "Not viewable ads, Excl. Geo, ?????",
  "cellType": "COUNT",
  "columnWidth": "CHAR_17",
  "cellAggType": "SUM",
  "cellAggColumn": "",
  "customMetricCategory": "CUSTOM_VIEWABILITY_QI"
},
{
  "columnName": "nonQualifiedForViewabilityPct4",
  "columnLabel": "% Non quality: not viewable, Excl. Geo, ?????",
  "cellType": "TWO_PRECISION_PERCENT",
  "columnWidth": "CHAR_17",
  "cellAggType": "WEIGHTED_AVERAGE",
  "cellAggColumn": "nonQualifiedAds4",
  "customMetricCategory": "CUSTOM_VIEWABILITY_QI"
},
{
  "columnName": "nonQualifiedForBrandSafetyAds4",
  "columnLabel": "Failed brand safety ads, Excl. Geo, ?????",
  "cellType": "COUNT",
  "columnWidth": "CHAR_17",
  "cellAggType": "SUM",
  "cellAggColumn": "",
  "customMetricCategory": "CUSTOM_VIEWABILITY_QI"
},
{
  "columnName": "nonQualifiedForBrandSafetyPct4",

},

  "columnLabel": "Invalid traffic ads, Excl. Geo, ?????",
  "cellType": "COUNT",
  "columnWidth": "CHAR_17",

}

While running the repo in my local, build is failing with the following error:

Do I need to define anything else for this customMetricCategory? How can I get rid of this error?

TemplateColumn.java class

package com.integralads.crbworker.output.template.json;

import com.integralads.crbworker.excel.core.ReportCell;
import com.integralads.crbworker.excel.core.ReportColumnWidth;

public class TemplateColumn {

    private String columnName;
    private String columnLabel;
    private ReportCell.CellType cellType;
    private ReportColumnWidth columnWidth;
    private ReportCell.CellAggType cellAggType;
    private String cellAggColumn;

    public String getColumnName() {
        return columnName;
    }

    public void setColumnName(String columnName) {
        this.columnName = columnName;
    }

    public String getColumnLabel() {
        return columnLabel;
    }

    public void setColumnLabel(String columnLabel) {
        this.columnLabel = columnLabel;
    }

    public ReportCell.CellType getCellType() {
        return cellType;
    }

    public void setCellType(ReportCell.CellType cellType) {
        this.cellType = cellType;
    }

    public ReportColumnWidth getColumnWidth() {
        return columnWidth;
    }

    public void setColumnWidth(ReportColumnWidth columnWidth) {
        this.columnWidth = columnWidth;
    }

    public ReportCell.CellAggType getCellAggType() {
        return cellAggType;
    }

    public void setCellAggType(ReportCell.CellAggType cellAggType) {
        this.cellAggType = cellAggType;
    }

    public String getCellAggColumn() {
        return cellAggColumn;
    }

    public void setCellAggColumn(String cellAggColumn) {
        this.cellAggColumn = cellAggColumn;
    }
}

Also there is a TemplateCustomMetricheading.java class also define for the customMetricCategory

package com.integralads.crbworker.output.template.json;

public class TemplateCustomMetricHeading {
    private String headingName;
    private CustomMetricCategory customMetricCategory;

    public String getHeadingName() {
        return headingName;
    }

    public void setHeadingName(String headingName) {
        this.headingName = headingName;
    }

    public CustomMetricCategory getCustomMetricCategory() {
        return customMetricCategory;
    }

    public void setCustomMetricCategory(CustomMetricCategory customMetricCategory) {
        this.customMetricCategory = customMetricCategory;
    }
}

Answer

There are two ways to get rid of the error:

Add the missing field private CustomMetricCategory customMetricCategory to the TemplateColumn class and implement related getter/setter to comply with the input JSON:

public class TemplateColumn {

    private String columnName;
    private String columnLabel;
    private ReportCell.CellType cellType;
    private ReportColumnWidth columnWidth;
    private ReportCell.CellAggType cellAggType;
    private String cellAggColumn;
    private CustomMetricCategory customMetricCategory;
// ... getters/setters
}

Ignore failing on unknown properties when deserializing instances of TemplateColumn class.

@JsonIgnoreProperties(ignoreUnknown = true)
public class TemplateColumn {
...
}
