Please flush Magento cache using below command

php bin/magento cache:flush

& confirm if that solves the problem.

[rav-redchamps]

If this command still triggers error then try removing cache directory directly

rm -rf var/cache

[AndrewRMillar]

@rav-redchamps Thanks for your reply. I was under the impression that setup:upgrade cleared the cache, that is why I did not perform that step. But apparently that is an essential step for this module. After flushing the cache the issue was resolved in my local development environment.

I can't imagine that flushing the cache is not part of our deploy pipeline. I will test it in a review deployment. And get back to you, when this step resolves this issue on review I will close this issue.

@AndrewRMillar I hope this issue is resolved, so closing it. Please feel free to reopen if you are still facing it.
