BREAD browse error on large JSON text column: mb_strlen() expects parameter 1 to be string, array given

[damms005]

Version information

• Laravel: v8.37.0
• Voyager: v1.4.x-dev
• PHP: 7.4
• Database: MySQL 8.0

Description

When I navigate to a BREAD's browse page, and a record has two large JSON string values (of about 2024 characters each) for a text column (text COLLATE utf8mb4_unicode_ci NOT NULL), the BREAD browse fails with the error below logged:

[2021-04-17 08:08:04] xxx.ERROR: mb_strlen() expects parameter 1 to be string, array given (View: /home/enniqnva/idvouch.com/vendor/tcg/voyager/resources/views/bread/browse.blade.php) {"view":{"view":"/home/enniqnva/idvouch.com/vendor/tcg/voyager/src/../resources/views/bread/browse.blade.php","data":{"errors":..<a really long but nothing unusual, normal dump here>}

Steps To Reproduce

1. Create a table in the database with about 9 columns. Ensure that two out of the columns are defined as text COLLATE utf8mb4_unicode_ci NOT NULL
2. Create BREAD for the table from Voyager
3. Create a record that has a JSON string of about 2024 characters in each of the two text columns defined in Step # 1 above
4. Navigate to the BREAD's browse route
5. Error 505

Additional context

I guess the most important step in reproducing this is to ensure that at least 2 of the columns are text COLLATE utf8mb4_unicode_ci NOT NULL and a row has JSON string stored in both columns, with each of the JSON string not less than 2024 characters
