Hi @ROxX ,

The error clearly states that you should include the following line in your package.xml file:

<member_of_group>rosidl_interface_packages</member_of_group>

Refer to the course instructions on how to create a custom interfaces to know where to add the above mentioned line.

Your package.xml file should include the above line as shown below:
Between <depend> and <test_depend> tags.

<?xml version="1.0"?>
<?xml-model href="http://download.ros.org/schema/package_format3.xsd" schematypens="http://www.w3.org/2001/XMLSchema"?>
<package format="3">

  <export>

  </export>
</package>

This should solve your issue. let me know if this does not fix your issue.
