SourceHanSans-Medium.ttc has the following metadata:

...
 ["fontname"]="SourceHanSans-Medium",
...

and four subfonts:

(0):
   ["postscriptname"]="SourceHanSans-Medium",
(1):
   ["postscriptname"]="SourceHanSansK-Medium",
(2):
   ["postscriptname"]="SourceHanSansSC-Medium",
(3):
   ["postscriptname"]="SourceHanSansTC-Medium",

In this case, ("postscriptname" of the subfont 0) == ("fontname" of SourceHanSans-Medium.ttc).
Therefore, "Invalid TTC index number" error does not occur.
If you delete subfont 0 from the ttc, you may get the error.
