error occurs in step - invert_network

[Liuqi2002519]

Description of the problem
I am using sentinel data generated by ISCE2 2.6.3 for mintpy processing and have successfully imported the data.
The file data.rsc has been successfully generated in the reference directory. I also use them in the same virtual environment.
However, an error occurred in the 'invent_network' step and requested the following 'ALOOKS' information.

Full script that generated the error

smallbaselineApp.py smallbaselineApp.cfg

This metadata (ALOOKS) is generated during the load_data step, and is saved in the data.rsc file. If both isce2 and mintpy are installed in the same environment, please delete the data.rsc file and inputs folder and rerun load_data step. If the error still persist, it probably because of some file missing in the merged/geom_reference folder, please use the Fernandina example dataset as reference for checking.

Thank you, Mr. Zhang. I did not delete data.rsc, and when I re-imported the data, I saw that data.rsc had been regenerated and there was also an ALOOKS field inside it.
