You might see the following error messages "Not supported content type" or "The value could not be rendered". This is due to a breaking change introduced to retrieve the raw structure of the R-groups and get rid of the need to be authenticated to LiveDesign to render them. The content-type of these columns changed from "image/discngine-livedesign-url" to "chemical/x-daylight-smiles". As a consequence, the renderer "Discngine LiveDesign Image" used previously is not appropriate anymore. ## Resolution For each visualization and axes where a RX (SAR) column is used, change the renderer used to **Discngine Molecule Renderer**.
