Parsing Error?

[FrankDatagroup]

Sorry for the maybe stupid question, I am not a scripting guy but was glad to be able to use the safemanagement script successfully last year. However, now I wanted to use it with parameter Addmembers on the same machine which doesn't work with the version I had. So I downloaded the last version (in which it should work again as I read here in the release notes) but now I am getting

ParserError: C:\Users........v\Safe-Management_new.ps1:41 Line | 41 | … script type="application/json" id="client-env">{"locale":"en","featur … | ~~~~~ | Unexpected token ':"en"' in expression or statement

Is it me doing something wrong or is that a bug?

Thanks for any hints, Frank
