Summary
The root cause of this issue is that both ImportDependency and ModuleHotAcceptDependency can be used to generate a module (e.g., ./info.json). ImportDependency includes import attributes, but ModuleHotAcceptDependency does not. If ModuleHotAcceptDependency appears first, the generated module (./info.json) will lack import attributes, which means it can’t match type: "json". As a result, it gets treated as a JavaScriptModule, leading to a parsing error.
