[couchbase] IncompatibleClassChangeError on android

I get this issue when saving a document to the couchbase in Batch as follow:

this.database.inBatch(() => {
    documents?.forEach((document) => {
      const id = document._id ?? document.id
      let resultId
      if (id) {
        resultId = this.saveDocument(document, id)
      } else {
        resultId = this.saveDocument(document)
      }

      if (resultId) ids.unshift(resultId)
    })

env:

ns: 8.4.0
couchbase: 1.4.0
os: android
@nativescript/android: 8.4.0

I appreciate any help.

Start with the database.inBatch call and the supplied Android stack trace, using the listed NativeScript, Couchbase, and Android versions as the reproduction context. Investigate the interaction between Couchbase Lite UnitOfWork and the generated Runnable implementation; done means saving documents in a batch no longer raises IncompatibleClassChangeError.
