Why am I getting the error: "TypeError: Object.fromEntries is not a function?" when running a unit test?

Question

JavaScript

I have this method: "dataToExportInFile" it works correctly, but when I want to write a unit test for this method, I get an error: TypeError: Object.fromEntries is not a functioneven when I want to console the value of this method in the unit test. Please tell me what is the problem and how to solve it.

dataToExportInFile() {
            if (this.dps.length === 0 || this.legends.length === 0) {
                return null
            }
            const extractLegendsValue = Object.fromEntries(this.legends.map(n => [n.id, n])) // на эту строку ругается 
            const mergeData = this.dps.map(n => ({ ...n, ...extractLegendsValue[n.y] }))
            const formattedData = mergeData.map((en) => {
                const extractAggregator = en.id.substring(en.id.lastIndexOf("_") + 1)
                return {
                    time: new Date(en.timestamp).toISOString(),
                    entityId: en.isAggregated ? "" : en.entityId,
                    name: en.isAggregated ? `${en.text} (${this.friendlyAggregatorNames[extractAggregator]})` :
                        en.secondaryText,
                    value: en.value,
                    entityName: !en.isAggregated ? en.text : ""
                }
            })
            return {
                value: {
                    mime: "text/csv",
                    data: formattedData,
                    friendlyHeaderNames: ["Time", "Entity ID", "Metric Name", "Value", "Entity Name"]
                }
            }
