We have recently released version 1.6.0 of Beams for Android - this updates our Moshi dependency from version 1.8 to 1.9. Versions 1.8 and 1.9 of Moshi are incompatible: this means any users on Moshi v.1.8 who upgrade Beams to v1.6.0 will encounter errors.
Similarly, any Moshi users who upgrade to v1.9 without upgrading their Beams version to 1.6.0 will encounter issues.
If you are encountering errors after upgrading Beams please ensure you upgrade Moshi. If this is not possible then you can continue to use Beams version 1.5.1 until such a time as you can upgrade Moshi.
