Cannot read property 'name' of undefined

[wstcyx]

In version 5.90.1 of webpack, an error is reported in FlagDependencyExportsPlugin.js, and the error content is as follows:

//lib/node_modules/@haier/packi/node_modules/webpack/lib/FlagDependencyExportsPlugin.js:189
name = exportNameOrSpec.name;
^
TypeError: Cannot read property 'name' of undefined
at mergeExports (//lib/node_modules/@haier/packi/node_modules/webpack/lib/FlagDependencyExportsPlugin.js:189:38)

I printed the exports and indeed found some undefined. However, I do not know what FlagDependencyExportsPlugin.js is used for. Please fix this issue as soon as possible.
