Duckduckgo wait_for_results selector doesn't work in case of no results

[PinkSheep]

Hello
It seems like the selector you are currently using to scrape the Duckduckgo Result Page is not properly working in the case that the search doesn't produce any results:

[i] duckduckgo scrapes keyword ... on page 1
Problem with scraping ... in search engine duckduckgo: TimeoutError: waiting for selector ".result__body" failed: timeout 10000ms exceeded

I think the issue here is the selector you are using:

async wait_for_results() {
        await this.page.waitForSelector('.result__body', { timeout: this.STANDARD_TIMEOUT });
    }

If the search produces no results, the Duckduckgo Results Page doesn't have a div with the class .result__body.
As a fix I suggest using one of the following selectors instead (I have not tested it though, but they are present in both cases):

#links
.serp__results
