X_ACTION_PATH_DERIVED_EARLY
Means
a path was derived before pathStyle changed
Typical cause
a module-level derivePath(name).path ran before defineApi declared the style, so that module holds a URL no route serves
Fix
derive the path where it is used — inside the component or function, never in a module-level const — or import the module that calls defineApi({ http: { pathStyle } }) (apps/web/api/index.ts) before the one that derives it
