Error in patch ^5.0.4

[worka]

TypeError: Cannot read property 'startTag' of undefined
at /****/node_modules/gulp-inject/src/inject/index.js:126:29

UPD:
Error when starttag: '{* inject:vendors.js *}'. If isset dot. If . swap on :, then all norm.

removing periods from my start and end tags fixed my problem also. Thanks, @worka!
