asset/invalid-script
A Script can’t be bundled: it isn’t valid JavaScript or TypeScript, or isn’t UTF-8, or it imports a name the other module doesn’t export, or a <script type="module"> names a file that is no Script. A Script is a .ts, .js, .mts or .mjs file.
Example
let x = ;
Fix
Fix the code at the reported place. Here the variable needs a value.
