fint fromDefinition() method and then add debug code to find column name as below , we have addedd (debugging) code inside

{
$type = $data['type'];
if (!isset($this->definitionProcessors[$type])) {
/* Starts Add Code for Debug */
echo "<pre>";
print_r($data); exit();
/* Code End for Debug */
throw new \InvalidArgumentException(
sprintf("Cannot process definition to array for type %s", $type)
);
}
$definitionProcessor = $this->definitionProcessors[$type];
return $definitionProcessor->fromDefinition($data);
}
Step [2] – Runsetup:upgrade command and you will get an array of column data in the console. so from this array, you will get the name of the column from your third party extension table.
Now from that table please change column’s data type “tinytext” to “text”
