Invalid signature error 401 REST API magento 2

Hello. I’m trying to create a request to magento 2 REST API. I use oauth and have all tokens (consumer, consumer secret, token and token secret). I need to pass param like this: http://devdocs.magento.com/guides/v2.1/howdoi/webapi/search-criteria.html

My code:

const optionsToRequest = {
        url: `http://host/rest/V1/customers/search`,
        json: true,
        oauth: {
        consumer_key: CONSUMER_KEY,
        consumer_secret: CONSUMER_SECRET,
        token: TOKEN,
        token_secret: TOKEN_SECRET
    },
    qsStringifyOptions: {
            encode: false,
    },
    qs: { 'searchCriteria[filter_groups][0][filters][0][field]': 'email'}
};

request.get(optionsToRequest)
        .then(res => console.log(res));

and when i’m creating request then get response with error {"message":"Invalid signature"}. searchCriteria param looks like: searchCriteria[filter_groups][0][filters][0][field]=email. I also tried to create a query in POSTMAN and there everything is ok. I don’t understand this. Where is the mistake? The entire query should look like this: http://host/rest/V1/customers/search?searchCriteria[filter_groups][0][filters][0][field]=email
