  For a non-archimedean local field $F$ and a connected reductive group $G$
over $F$ equipped with a parabolic subgroup $P$, we show that the dualizing
complex on $\mathrm{Bun}_P$, the moduli stack of $P$-bundles on the
Fargues--Fontaine curve, can be described explicitly in terms of the modulus
character of $P$. As applications, we identify various characters appearing in
the theory of local and global Shimura varieties, show the Harris--Viehmann
conjecture in the Hodge--Newton reducible case, and carry out some computations
of the geometric Eisenstein functors for general parabolics.
