Error running SAGA NextGen plugin's "Points to lines" tool

Question

I am using QGIS 3.30.1 and am attempting to use the SAGA NextGen plugin to access SAGA processing algorithms, in particular the "convert points to lines" tool. I am using SAGA 7.3.0 installed from Linux Mint repositories. I am getting the following error (see paste below.)

Am I using the wrong version of SAGA?
