+! LaTeX3 Error: Command hook `cmd/textbf/middle' invalid.
+(LaTeX3)        The hook should be `cmd/textbf/before' or
+(LaTeX3)        `cmd/textbf/after'.
+For immediate help type H <return>.

+l. ...\AddToHook{cmd/textbf/middle}{error}
+You tried to add a hook to command \textbf, but `middle' is an invalid
+position. Only `before' or `after' are allowed.
+! LaTeX3 Error: Command `\undefined' cannot have hooks because it doesn't
+(LaTeX3)        exist.
+For immediate help type H <return>.
+ ...                                              
+l. ...\AddToHook{cmd/undefined/before}{error}
+You tried to add a hook to `\undefined', but LaTeX was not able to add the
+hook to that command because `\undefined' doesn't exist.
+! LaTeX3 Error: Command `\detokenize' cannot have hooks because it is not a
+(LaTeX3)        macro.
+For immediate help type H <return>.

+l. ...\AddToHook{cmd/detokenize/before}{error}
+You tried to add a hook to `\detokenize', but LaTeX was not able to add the
+hook to that command because `\detokenize' is not a macro.
+! LaTeX3 Error: Command `\__hook_cmd_begindocument_code:' cannot have hooks
+(LaTeX3)        because it doesn't exist.
+For immediate help type H <return>.

+! LaTeX3 Error: Command `\mycmd' cannot have hooks because it can't be
+(LaTeX3)        retokenized cleanly.
+For immediate help type H <return>.
