I hit that mine too with my first implementation of pass1(), and was a little frustrated that the tree wasn't accepted and I had to refactor.
That said, and to be fair, the grammar for expression and term does define the order the tree should be built in, altough it could be a nice gesture to explicitly state the associativity in the description too.

But your tree does not seem to conform to the associativity described with the grammar syntax? The grammar does not allow for
expressionon the right.
