Hmm. What version of the JS SDK are you using?

[elazar]

@eli-darkly 2.1.0. Suppose we could try upgrading. Any idea if this was a known issue in that version or versions since?

[eli-darkly]

It's not something we've seen before as far as I know, but knowing the version helps in tracking down the exact code path that's responsible.

Also, could you email your account name to eli@launchdarkly.com so we can try to reproduce this problem with your particular flag data?
