There are some VRC Components and TMP Components that don't have specified generic T types in an internal dictionary preventing the usage of
GetComponent<TMP_InputField>()
.
For those reading this and needing an alternative in UdonSharp you can use the other two:
GetComponent("TMP_InputField")
or
GetComponent(nameof(TMP_InputField))
and
GetComponent(typeof(TMP_InputField))
.
UdonGraph variants of this issue are shown in the provided images.
