msgid not found .the msgid in your example is incorrect.it is a 64-bit integer.

thank you!! you are right, i checked raw message and found that msgId is "8355831940407814566", but when parsing into json in nodejs, BigInt still lost some bits, so i got "8355831940407814144n". And then when i called toString, it became "8355831940407814144"!
