You said you read the writings and saw no errors. The only way you could know there were no errors, which are matters of technical accuracy, is to know the technical facts yourself. I can tell you, there are technical errors in his writings. They have errors. Inspiring faith, has little to do with technical accuracy.
Do you believe humans are not animals, that humans were not the product of evolution from earlier animal species? If so, that is a technical error. Yet, Baha'u'llah taught this, didn't he? And saying that one day science will agree with the prophet, is utterly un-satisfying to the rational mind, or faith. If you felt it was infallibly true because it inspired you like the warmth of the sun on your skin, that is an error of both the facts and faith. Both what you read and what you subsequently believed contain errors of fallibility.
If you get rid of the unnecessary notion of infallibility, the problem goes away. He can have been wrong about evolution, and still speak other truths that have meaning to you. Otherwise, you're tying a cement block around the feet of faith and tossing it into the river of facts to either swim or drown in its waters. That's unfortunate.
