Is there any restriction in Magento 2 with the length of the Vendor name for minimum of 3 ?

I have a vendor say: AB_Test

after upgrading the module, i get:

Exception #0 (Magento\Framework\Exception\LocalizedException): Invalid Document 
Element 'add', attribute 'title': [facet 'minLength'] The value 'AB' has a length of '2'; this underruns the allowed minimum length of '3'.
Line: 26

And other modules which are under 'AB' works fine.

Is it any xml issue or is it a restriction?

I do not get proper solution over the net for this issue.



<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../../../Backend/etc/menu.xsd">
    <add id="HM_Brand::brand" title="Brand" module="HM_Brand" sortOrder="40" resource="HM_Brand::brand" parent="HM_All::hm_all"/>  
    <add id="HM_Brand::brand_new" title="Add New Brand" module="HM_Brand" sortOrder="10" parent="HM_Brand::brand" action="hmbrand/brand/new" resource="HM_Brand::brand"/> 
    <add id="HM_Brand::brand_manage" title="Manage Brands" module="HM_Brand" sortOrder="20" parent="HM_Brand::brand" action="hmbrand/brand/index" resource="HM_Brand::brand"/>
    <add id="HM_Brand::brand_group_manage" title="Manage Groups" module="HM_Brand" sortOrder="40" parent="HM_Brand::brand" action="hmbrand/group/index" resource="HM_Brand::group"/> 
    <add id="HM_Brand::configuration" title="Settings" module="HM_Brand" sortOrder="50"
        parent="HM_Brand::brand" action="adminhtml/system_config/edit/section/hmbrand" resource="HM_Brand::config_brand"/>

  • Invalid document means there some xml issue. – Prasanta Hatui Feb 27 '17 at 11:35

It is an XML restriction in your menu.xml.

Indeed, according to the menu.xsd validation schema there are several restrictions to the attributes of the add element, in your case:

<xs:simpleType name="typeTitle">
            Item title attribute minimal length 3 symbol
    <xs:restriction base="xs:string">
        <xs:minLength value="3" />
        <xs:maxLength value="50" />

The title length must be between 3 and 50 characters

  • I have updated menu.xml in my question, since i have anywhere not used or set the min lenght, i guess its set in Magento/Backend/etc/menu.xsd !!! – Sushivam Feb 27 '17 at 12:17
  • @SachinS yes that's correct – Raphael at Digital Pianism Feb 27 '17 at 12:23
  • So suggested way is we have to give min 3 length in our namespace since we cannot change the core file – Sushivam Feb 27 '17 at 12:24
  • @SachinS yup 100% correct – Raphael at Digital Pianism Feb 27 '17 at 12:25
