They formed farther out like Jupiter but then migrated inward.
"The theory was not based on accurate observations" does not describe a scientifically reasonable explanation for why the nebular theory failed to predict the existence of hot Jupiters. The actual reason is that hot Jupiters were not part of the original models due to limitations in our understanding of planet formation and migration processes.

The exoplanets called "Hot Jupiters."
Astronomers explain the orbit of hot Jupiters, gas giant exoplanets located close to their stars, through theories of planetary migration. These planets likely formed further from their stars and later migrated inward due to gravitational interactions with the protoplanetary disk or through interactions with other bodies. Tidal forces and the dissipative processes in the disk can also help circularize their orbits. Additionally, some hot Jupiters may have formed in situ through rapid gas accretion in their current locations.
Many extrasolar planets are called hot-Jupiters because they are gas giants like Jupiter but much closer to their parent stars, leading to high surface temperatures. Their close proximity to the star results in rapid orbital periods and high levels of irradiation, causing them to be hot compared to Jupiter in our solar system.

Models suggest that the clouds on hot Jupiters could be composed of minerals like corundum and silicates, as well as exotic compounds such as titanium oxide and aluminum oxide. These clouds may form due to strong winds, vertical mixing, and high temperatures in the atmospheres of hot Jupiters.

Hot Jupiters may have migrated close to their stars due to interactions with the protoplanetary disk during their formation, gravitational interactions with other planets, or tidal forces from the star.

Many newly detected extrasolar planets are called hot Jupiters because they are large, gaseous planets with characteristics similar to Jupiter, but they orbit very close to their host star. This proximity to their star causes them to have high surface temperatures, hence the term "hot."

Planets like HD 189733 b, sometimes called "hot Jupiters" are one of the most common types of planets to be detected, largely because they are the easiest to detect. Such planets likely form at a great distance from their parent stars, but their orbits decay, bringing them extremely close to their stars. Hot Jupiters often slowly lose their atmospheres.
The availability of the hot mocha at McDonald's may vary by location and time of day. It is best to check with your local McDonald's restaurant to see if they currently offer hot mocha on their menu.
The discovery of hot Jupiters has challenged our understanding of planetary formation in our own Solar System. Their presence suggests that the processes that lead to the formation and migration of giant planets may be more complex and varied than previously thought, leading scientists to reevaluate existing models of planetary formation and migration.
