ts.transpileModuleerases any value ofnoEmitfrom the incoming compiler options, but still creates a program that does option validation. One validation is thatallowImportingTsExtensionsrequiresnoEmitto be set, so including this option intranspileModulecalls was always an error. The fix is to eraseallowImportingTsExtensionstoo—since its only purpose is to silence an error in checker code that doesn‘t run in transpilation, it’s not necessary to include in the first place. It can be completely ignored in transpilation.
