Custom Fields Error ?

[codeboy]

Hello there,
I created custom fields. Everything works, but it does not add any such space to the database. How can I solve this?

Actions I have made
1- Create custom file --> /custom/Espo/Custom/Resources/metadata/fields/{field-type}.json
2- Create custom file --> client/custom/src/views/fields/{field-type}.js

I clear cache and re-build then CTRL + F5.

[2018-09-13 09:03:14] Espo.ERROR: API [GET]:/:controller/:id/stream, Params:Array (     [controller] => Lead     [id] => 5b558ff5573d88407 ) , InputData:  - SQLSTATE[42S22]: Column not found: 1054 Unknown column 'lead.nationalNumber' in 'field list' [] []

Thanks in advance for your help!
