@bitshadow Thanks for reporting, this was fixed in PR #611. It will be included in the next release of this SDK and then will be included in the next react native SDK update after.

In the mean time the issue can be avoided by making sure you don't call sendTags with a empty JSON object as this triggers null error. Thanks.
