Deprecated preg_match_all() in functions-view_template

[andrewwerth]

Description

On a single item custom post page, using pods shortcode [pods field="fieldname"] produces a warning in debug mode:

Deprecated: preg_match_all(): Passing null to parameter #2 ($subject) of type string is deprecated in /var/www/html/wp-content/plugins/pods/components/Templates/includes/functions-view_template.php on line 723

Version

3.0.10

Testing Instructions

I don't have a way to provide step-by-step instructions to repeat this error. I have a page for displaying items of a custom post type created with Pods and there's a Template for that Single Item: PostTypeName. Within the template, there are two paragraph fields that use shortcodes to pull fields from the DB:
[pods field="fieldname1"] [pods field="fieldname2"] ...etc...

The information is displayed properly on the website, but with debug mode turned on the error messages appear. (Also note that in addition to the preg_match_all() deprecation message, there's also one for str_replace() on line 828 of functions-view_template.php, as shown in the screenshot.
