magento2 – There has been an error processing your request: “0”:”Unable to serialize value. Error: Malformed UTF-8 characters, possibly incorrectly encoded”

I am attempting to set up my local environment for Magento. When I try to view the front end, I get the following error on the page:

There has been an error processing your request

Exception printing is disabled by default for security reasons.

Error log record number: 4982d0e3c31863370d845d5635c2d16b81705475bfaa31edbd462354d0f17305

The log states the following:

{"0":"Unable to serialize value. Error: Malformed UTF-8 characters, possibly incorrectly encoded","1":"#1 Magento\Framework\App\PageCache\Kernel->process() called at (vendor/magento/module-page-cache/Model/Controller/Result/BuiltinPlugin.php:96)n#2 Magento\PageCache\Model\Controller\Result\BuiltinPlugin->afterRenderResult() called at (vendor/magento/framework/Interception/Interceptor.php:146)n#3 Magento\Framework\View\Result\Page\Interceptor->Magento\Framework\Interception\{closure}() called at (vendor/magento/framework/Interception/Interceptor.php:153)n#4 Magento\Framework\View\Result\Page\Interceptor->___callPlugins() called at (generated/code/Magento/Framework/View/Result/Page/Interceptor.php:130)n#5 Magento\Framework\View\Result\Page\Interceptor->renderResult() called at (vendor/magento/framework/App/Http.php:120)n#6 Magento\Framework\App\Http->launch() called at (generated/code/Magento/Framework/App/Http/Interceptor.php:24)n#7 Magento\Framework\App\Http\Interceptor->launch() called at (vendor/magento/framework/App/Bootstrap.php:261)n#8 Magento\Framework\App\Bootstrap->run() called at (pub/index.php:40)n","url":"/","script_name":"/index.php","report_id":"4982d0e3c31863370d845d5635c2d16b81705475bfaa31edbd462354d0f17305"}

I have attempted to compile and reindex with no luck. I am fairly certain file permissions have been set up correctly, as I used the docs to set them up with these commands:

cd <magento_root>
sudo find var vendor pub/static pub/media app/etc -type f   -exec chmod g+w {} +
sudo find var vendor pub/static pub/media app/etc -type d   -exec chmod g+ws {} +
sudo chown -R :<web server group> .
sudo chmod u+x bin/magento

What am I missing? Any help is appreciated. I am new to Magento, so please tell me if I need to provide any more information.
