How to handle mutliple responses using Promise.all if one promise fails?

Question

Trying to combine response either (success or failure) both scenario with below code its returning empty object because one of the handler has an error.

1- How to combine responses using Promise.all if one promise fails i want to have that promise error part of final response?

2- what would be right approach to have this problem resolved.

main.ts

private async execute(@Request() request: ExpressRequest): Promise < any > {
        let _combineData: any = [];
        const accountBalanceRequest = request.body.getAccountBalanceRequest;
        try {
            const _data1 = await this.Handler1(accountBalanceRequest);
            const _data2 = await this.Handler2(request);
            const combinedResponses = await Promise.all([_data1,_data2].map((callback) => callback(val))
                .then(values => {
                    combineData = values;
                })
                .catch(err => {
                    console.log(err);
                }); _
            }
            catch (err) {
                return err;
            }
            return _combineData;
        }

thats how i wanted to build the response

details: [{
            success response from first promise handler
        }, {
            error from 2n d promise handler
        }]
