WebSep 19, 2013 · The nitrogen as two aromatic bonds and thus a bond order sum of 3 (1.5 + 1.5). This is a default valence for nitrogen and so there is no implicit hydrogen. The oxygen also has the bond order sum of 3 which exceeds it's maximum specified valence (2) and again there are no hydrogens. c1n ( [H])ccc1.

This is because of the co-ordinate bond present in the molecule which RdKit doesn't support. RdKit will treat it as a single bond which will raise the valency of both the Nitrogen atoms to 4 and hence an invalid molecule. Here's the same molecule generated from other sources:
