To install your component to Joomla 4.2.2 you need to convert it to Joomla 4 from Joomla 3 in the JCC there is a setting to do that.
Follow the following steps:
1. Go to your component where you are facing an issue Click on Edit Component, and select Joomla Version to Joomla 4
2. Give Namespace name
3. Click on Save Component
Now you are ready to download and install the component on the Joomla 4 instance.
By following the above steps to your component we were able to install it on Joomla 4 instance, please confirm.
