Hi Kyky,

That's definitely an odd error.   Maybe you had previously built an older version of DSpace and it's encountering some older versions of dependencies?

If so, you can run "yarn clean", then "yarn install" and "yarn build:prod" again.

If that still doesn't work, you might try reinstalling Yarn or Node.  This error almost sounds like Yarn itself is having a failure.  Maybe it didn't get installed properly?

Hi,

Thank you for the suggestion I've tried it.
I am re-install the yarn and also node but it still didn't fix the problem and I just notice, every time i tried to "yarn run build:prod" the error always different. But it still said invalid token, But the error line/file is always different every time.

Hopefully you have another suggestion for this

Kyky
