There was a possibility that the Hubble Telescope was not able to clearly resolve the luminosity of Cepheid variable stars which are being used as one of the markers to determine the expansion rate of the universe. It was thought that the Hubble might not be able to get a clear image through the interstellar dust and all the brightness of the other stars crowding around the target stars which could skew the results. The James Webb Space Telescope can clearly see through the dust and clearly resolve the stars around the target stars which showed that the results from the Hubble observations were accurate.
The observations of the universe are being made based on what can be seen. The effects of gravity are also measured by electromagnetic observations. The movements of physical bodies are derived from math calculations. The farther away stuff gets the more the results end up portraying a flat picture. The rules are bent to make each type of measurement fit the overall picture which is somehow connected to the mysterious effects of dark matter and dark energy.
This reminds me of of how Tycho Brahe used a complicated system of epicycles to explain all the visual observations of the planets as they revolved around the sun. He needed the complicated and apparently accurate epicycles to explain how the the planets moved around the sun, and the stars, sun, and moon moved around Earth, with Earth at the center of the universe,
