Thank you for contacting us about WebViewer. It looks like the “wasm” and “res” files aren’t currently publicly accessible. WebViewer will dynamically load resources depending on the document it’s trying to load. It looks like when WebViewer tries to load the resources from the folder, it’s getting 404 errors. Do the files it’s trying to load exist in that folders? Also what back end are you using? You might need to set it up to allow it to serve “res”, “mem”, and “wasm” files.
