What did Shay's rebellion convince colonial leaders that they had to change?

Shay's rebellion was mostly lead by farmers who were upset by their taxes and debts and decided to take matters into their own hands. They did not want their property taken from them, as this happened when they were not able to pay their debts and/or taxes, so they forced closure of multiple courts throughout Massachusetts. Blood was shed, and eventually Shay's rebellion caused the Constitutional Convention of 1787 which discussed changing the Articles of Confederation which maintained the weak government system and caused many problems. After this the Constitution was created.
