How can I get and implement waves publickey

Question

I am getting a error in my JavaScript code, which is requesting a public key from my Waves wallet. Can you guys help me to get that? It's the only thing preventing my code from running. I need the public key.

I have the public key here with me, I just need a way to implement that in my JavaScript code.

This is the error in Firebase after I deploy:

logs in Firebase:

Exception from a finished function: Error: Please provide either seed or senderPublicKey

in their API shows: https://testnode1.wavesnodes.com/api-docs/index.html GET ​/addresses​/publicKey​/{publicKey}

    const functions = require('firebase-functions');
    exports.distributeStakingRewards = functions.pubsub.schedule('every 1 minutes').onRun((context) => {
        const request = require('request')

        const assetID = 'xxx'
     
        request('https://testnode1.wavesnodes.com/assets/' + assetID + '/distribution', function(err, res, body) {

Javascript

You need to pass the publicKey whenever the request need it. Acording to the Swagger definition, it must be passed as URL parameter like so:

let publicKey = 'your-public-key';

request('https://testnode1.wavesnodes.com/addresses/publicKey/' + publicKey, function(err, res, body) {

});

SwaggerUI

If you want to test the request through the Swagger Interface you can press the button Try it out under the proper request, fill the required input with the public key and then press the button Execute.
