We withdrew because of information that was already 15 years out of date?
I'd understand if it showed that Iran was failing to live up to the JCPOA. But to withdraw based on what it had been doing back in 1999-2003, a decade before the agreement? That, I can't follow.

But it does show that, from the wiki:
According to journalist Yonah Jeremy Bob and nuclear expert Jeffrey Lewis, much of the key contents were already reported in past IAEA reports. However, the trove provided more clarity about Iran's specific goals for its arsenal,[12] and it proved that Iran violated the JCPOA, which prohibited Iran from engaging in any research and development activity and required full disclosure of all of Iran's nuclear program, including documentation

Actually it is hard to follow! Both governments made it as if because the evidence was found, US withdrew from the pact. However, the operation to gather the evidence was launched so as to give the US a valid reason to withdraw from the pact. The cause-effect is the other way around. Of course, everyone suspected that Iran wasn't keeping up the promise with or without evidence anyways. The evidence was needed solely to give the US president a political reason to dump a deal set by his predecessor.
