Hi, I keep getting this error when I try to click Update on the Schema tab. First I try to create a table. Then added the following columns: created\_by - user\_id\_on\_create last\_updated\_by - user\_id\_on\_update created\_on - timestamp\_on\_create last\_updated\_on - timestamp\_on\_update At this point I am still able to Update the table. Next I added a column id as binary with length of 36. Then I set this as the primary key and delete the example column that was created by default. When I hit Update now I get the error API Error Array to string conversion. Not sure what to do at this point. Appreciate any assistance. Thanks, Allen ---

Can you post the whole error? Also, what type of sql database is this? What version of DreamFactory and what operating system/install type? ---

That’s the only error message that comes up on the notification box on the upper left side of the page whenever I click Update. Details of my DF below: Admin Application Version: 2.0.1 DreamFactory Version: 2.0.1 Using MySQL 5.6 with Amazon RDS. Although, just wanted to point out that other than this error, everything seems to be working okay. Thanks, Allen ---

You should update to 2.0.2 I attempted to recreate your schema and had no trouble with the binary field. ---

> [@formerstaff](#): > > Sure.Installation and Upgrade instructions are available on the wiki. [Installation - DreamFactory](https://wiki.dreamfactory.com/DreamFactory/Installation#Upgrade) Upgrading to 2.0.2 fixed the issue. UPDATE: Had encountered others issues upon doing this. Some of which are: 1. Email service stopped working. Getting the error. > “message”: “Error processing password reset. Argument 1 passed to DreamFactory\Library\Utility\ArrayUtils::get() must be of the type array, null given, called in /opt/bitnami/apps/dreamfactory/htdocs/vendor/dreamfactory/df-core/src/Services/Email/BaseService.php on line 69 and defined” 1. Role service access particularly the Component was set to blank. Will try to re-install DF 2.0.2 UPDATE: Re-installing DF 2.0.2 fixed all issues. Regards, Allen
