Debezium postgres connector cannot handle making a new column required after updating it with a value

We have a liquibase changeset as follows

<changeSet id="add-optional-column">
		<addColumn tableName="a_table">
			<column name="a_column" type="BOOLEAN"/>
		</addColumn>
</changeSet>

<changeSet id="update-column">
		<sql>
			UPDATE a_table SET a_column = false
		</sql>
</changeSet>

<changeSet id="make-required" author="Dave S - Hendrik J">
		<addNotNullConstraint tableName="a_table" columnName="a_column" />
</changeSet>

Which adds an optional column, then updates it with a value, and then makes it required.

The 'a_table' also contains a row of data before the changesets execute.

When debezium is listening to postgresql while this executes we get into a situation where debezium complains that he receives a null value for a column which is required. See attached debezium log!

Probably a race condition where debezium gets change events for a situation before the value is set and debezium updates its metadata cache when the required constraint is already added.
