@cheerr did you manage to solve this? Are you using react-native-fetch-blob or are any of your dependencies using react-native-fetch-blob?

[nes123]

I am still having this problem and I am using react-native-fetch-blob

[yocokirk]

Interesting. I've got the same stack trace in bugsnag and using react-native-fetch-blob. I'll keep you updated if i find a solution

[chrusart]

This is a react-native-fetch-blob issue.
