Set this in settings.local.php so that it displays locally, but not on prod. The default Logging and errors should be 'None'.
// none - display none
// some - errors and warning

Set kint debug max level.
If kint is taking forever to load or crashing the page, try reducing the max level.
You will need to copy sites/example.settings.local.php to sites/default/settings.local.php (and ensure settings.php includes settings.local.php) or put this in your settings.php file: $settings['container_yamls'][] = DRUPAL_ROOT . '/sites/development.services.yml';.

// Just need to add lines 6-8 to it.

Debugging search API solr queries:
// You can output the Request object using kint/kpm, but it can be hard
// to figure out where to set the debugging code. The best place is in
// the executeRequest function in the following file:
// search_api_solr/src/SolrConnector/SolrConnectorPluginBase.php
Starting point for debugging ElasticSearch stuff, in the file
// src/ElasticSearch/Parameters/Builder/SearchBuilder.php:
// Add ksm at the end of build() and getSearchQueryOptions()
$node->field_example will return a FieldItemList object (or another class that extends FieldItemList
If you want to drill down to values under the field, you can add ->first() or leave it off and it'll automatically use the first item. This is true if the field is a single item or multi-values. Example: $node->field_example->target_id or $node->field_example->first()->target_id.
If the field is an entity reference, you can get the full entity: $node->field_example->entity (this gets the first entity if it's a multi-value).
On multi-value fields to get something other than the first you can use the array index: $node->field_example[1].
Entity reference
// Both of these return the same Entity ID value.
$node->field_ref->target_id;
$node->field_ref->first()->target_id;
// Get the full entity. "->entity" is only valid when the field is an entity reference.
$node->field_ref->entity;
// Get the value as an array: ['target_id' => '1'].
$node->field_ref->getValue();
// Will return null.
$node->field_ref->value;
URL
$node->field_url->uri;
$node->field_url->title;
$node->field_url->options; // Array of options.
$node->field_url->entity; // Returns null because it isn't an entity.
$node->field_url->getValue(); // Returns ['uri' => '', 'title' => '', 'options => []]
$node->field_url->value; // Returns null.
Text values
// Get the value as a string.
$node->field_text->value;
// Get the value as an array: ['value' => 'text'].
$node->field_text->getValue();
