Error on moving from webix_debug.js to webix.js

Hi,
my app run well with webix_debugg.js file but when i use webix.js file, I got this two errors and don’t build the window called:

Uncaught TypeError: Cannot read property ‘length’ of undefined
at Object.getConfig (webix.js:862)
at c.rj (webix.js:915)
at c.render (webix.js:911)

Uncaught TypeError: Cannot read property ‘header’ of undefined
at c.xt (webix.js:1160)
at c.hideColumn (webix.js:1159)

at Function.webix.ajax.$callback (webix.js:132)
at XMLHttpRequest.G.s.onreadystatechange (webix.js:127)
at XMLHttpRequest.onreadystatechange (client.js:1876)

I don’t have this error using webix_debug.js file.

Please help me to find what’s going wrong

perhaps you are using webix private method (starting with underscore _) in your code.
they are minified in the production version and this leads to error.

this error happens on new webix 5.4.3 debug file …

I check code parts running around this error, no methods beginning with “_” .

must rollback webix to 5.4.2 pro for only get running without error and only with the debug.js file

look like using ’ numberFormat=“1”, ’ in datatable column config making crash
