Migrate module, long text issue
Ok, just found the problem.

I was using this select:

$query = $this-&gt;getConnection()-&gt;select('j3_k2_items', 'n')
  -&gt;fields('n', array('id', 'title', 'fulltext'))
  -&gt;condition('catid', array(43, 45, 46, 51, 68, 72, 109, 117),'IN');


but the array inside the fields was the problem. When I removed it:

$query = $this-&gt;getConnection()-&gt;select('j3_k2_items', 'n')
  -&gt;fields('n')
  -&gt;condition('catid', array(43, 45, 46, 51, 68, 72, 109, 117),'IN');


Which was the same as doing a "SELECT *" the error gone and the migration worked!
