Read JSON Node from passed in string

I'm trying to centralize endpoints to a single JSON file in my api folder.

{ 
  EndPoint: {
     Action: {
        path1: '/thisispath1/{id}',
        path2: '/thisispath2/',
     }
}

What I want to do is get the path name kinda of like how useTranslations works.

    const t = useTranslations('Endpoint');
    const path = t('Acton.path1',1);
//path = '/thisispath1/1';

Not sure where to start with this.

It some what worked with the top level node. i.e. GetEndpoint('EndPoint'); returns

     Action: {
        path1: '/thisispath1/{id}',
        path2: '/thisispath2/',
     }

but not GetEndpoint('EndPoint.Action.path1',1); returns undefined

type EndPointKeys = keyof typeof endPoints;

export const GetEndPoint = (action: string, parameter: string) => {

//Think I have to a recursive keyof typeof here?

    return endPoints[action as keyof typeof endPoints];

};

What I ended doing:

import endPoints from '../service-end-points/service-constants.json';

const jsonPathToValue = (Points: any, path: string) => {

    let jsonData = Points;
    let newpath = path.replace(/\[(\w+)\]/g, '.$1'); // convert indexes to properties
    newpath = newpath.replace(/^\./, ''); // strip a leading dot
    const pathArray = newpath.split('.');
    let key = '';
    for (let i = 0; i <= pathArray.length; i++) {
        key = pathArray[i];
        if (key in jsonData) {
            if (jsonData[key as keyof typeof jsonData] !== null) {
                jsonData = jsonData[key as keyof typeof endPoints];
            }
        }
    }
    const finalPath = pathArray.slice(-1)[0];
    try {
        if (jsonData?.Actions[finalPath]) {
            return jsonData?.Actions[finalPath];
        }
    } catch (e) {
        return null;
    }
};

export const GetEndPoint = (path: string) => {
    const url = jsonPathToValue(endPoints, path);
    const HOST = process.env.CONSTELLATION_SERVICE_URL || null;
    if (!HOST) {
        throw new Error('SERVICE HOST NOT DEFINED');
    }
    return `${HOST}${url}`;
};
