Can't Login w/ Coinbase

I get an unsuccessful login and error (code below) when attempting to login w/ Coinbase social login. Googling around suggests that more data is sent back in the headers than what Bubble allows. Does anyone know how to avoid this error? Any help is appreciated!

Step-by-step instructions:

  1. Navigate to https://safetynetus.io/version-test/bitcoin?debug_mode=true
  2. Click “Sign up for UBI!”
  3. Authorize the Coinbase account
  4. After being redirected back to https://safetynetus.io/version-test/bitcoin?debug_mode=true I get the below error code and the user is NOT logged in.

Error code:
HPE_HEADER_OVERFLOW
