I try to change the type of the field customer_note in the quote table from varchar to text. I went the declarative way:


<?xml version="1.0" ?>
<schema xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Setup/Declaration/Schema/etc/schema.xsd">
    <table name="quote" >
        <column xsi:type="text" name="customer_note" />

Then I try the CLI command

bin/magento setup:db-declaration:generate-whitelist --module-name=VendorName_Module

The result:

Invalid Document
Element 'column', attribute 'length': The attribute 'length' is not allowed. 
Line: 59

The "Line 59" is inside the db_schema.xml in the "Quote" module of the org. magento 2 sources. Is this a known bug and is there any known work around for this? Or did I do something wrong?

Add info: my module.xml contains a

        <module name="Magento_Quote"/>

I solved it myself. There is an official bug report: https://github.com/magento/magento2/issues/26155

The bug is solved in the current 2.4.1 release. But just in the way, that they changed the 'Quote' db-schema.xml.

Well, that is nice, but did why did the official way using the declarative way did not work?
