PHP Fatal error: Uncaught Error: Call to undefined method GuzzleHttp\Utils::chooseHandler()

Any ideas why I'd have this showing whenever I try to use the library?

PHP Fatal error: Uncaught Error: Call to undefined method GuzzleHttp\Utils::chooseHandler()

Everything was working great and then suddenly this, repeatedly.

I think the problem is with guzzleHTTP package.
Try removing vendor folder and composer.lock file and try installing vendor again.

Thanks for the reply.

I've tried this and it doesn't seem to solve it. I did a ton of searching on Google and StackOverflow and lots of people having the same issue but no solutions that seem to solve the issue.

Is the zoom library expecting/specifying a specific version that's maybe not the one being loaded because of other libraries that might loaded first?
