"expansionMap" not supported

[ZababurinSergei]

I wanted to use the library.
But when I connected it as a module I got an error.
Here's the part of the code that doesn't work and get one error

details: "\"expansionMap\" not supported."
type:"jsonld.OptionsError"

  const unmappedProperties = [];

    const expansionMap = info => {
      if (info) {
        if (info.activeProperty) {
          unmappedProperties.push(
            `${info.activeProperty}.${info.unmappedProperty}`
          );
        } else if (info.unmappedProperty) {
          unmappedProperties.push(info.unmappedProperty);
        }
      }
    };


    
    // Remove all keys not present in the jsonld context
    const expanded = await jsonld.expand(jsonldDoc, {
      documentLoader,
      expansionMap,
    });

How can i fix this problem ?

Hi! I don't maintain this lib anymore but happy to help debug this. Can you provide a code example to repro the error?
