the boss isn't chatty

[QuinquaGeek De Twitch]

Hello,
I'm trying to customize a creature and bring it to life with scripts (I'm using singleplayerproject ver 2.3.7 core 28 db 19 web 11 - WoW Classic).
The first event works well: the NPCs appear as they should but whatever I do the boss remains totally silent and refuses to start dialogues.
I tried a number of modifications to the second event, copying and pasting existing data, but to no avail. There aren't many clear tutorials on how to use creature_ai_scripts.
If anyone can help me here, I'd appreciate it.

First Event (ok) :
INSERT INTO `creature_ai_scripts` (`id`, `creature_id`, `event_type`, `event_inverse_phase_mask`, `event_chance`, `event_flags`, `event_param1`, `event_param2`, `event_param3`, `event_param4`, `event_param5`, `event_param6`, `action1_type`, `action1_param1`, `action1_param2`, `action1_param3`, `action2_type`, `action2_param1`, `action2_param2`, `action2_param3`, `action3_type`, `action3_param1`, `action3_param2`, `action3_param3`, `comment`) VALUES (40000101, 400001, 0, 0, 100, 1025, 4000, 9000, 4000, 9000, 0, 0, 12, 400014, 4, 60000, 0, 0, 0, 0, 0, 0, 0, 0, 'vilain');

Second Event (NO ok)
INSERT INTO `creature_ai_scripts` (`id`, `creature_id`, `event_type`, `event_inverse_phase_mask`, `event_chance`, `event_flags`, `event_param1`, `event_param2`, `event_param3`, `event_param4`, `event_param5`, `event_param6`, `action1_type`, `action1_param1`, `action1_param2`, `action1_param3`, `action2_type`, `action2_param1`, `action2_param2`, `action2_param3`, `action3_type`, `action3_param1`, `action3_param2`, `action3_param3`, `comment`) VALUES (40000102, 400001, 4, 0, 15, 0, 0, 0, 0, 0, 0, 0, 1, 20000, 20001, 20002, 0, 0, 0, 0, 0, 0, 0, 0, 'Southshore Crier - Yell on Spawn');
