Error: Cannot create URL for blob

[acostalima]

The issue apparently lies in NativeModules. The import is undefined and, thus, BLOB_URL_PREFIX remains null. This patch fixes the problem.

Has anyone else experienced this as well? It's happening on RN v0.63.2 on my end.
@charpeni, let know if you want me to open a PR to address this.

Thanks for sending this!

Hmm, do you have a repro case? 🤔

We should make sure to cover this with tests.

Hmm, do you have a repro case?

More or less. 😅
I'll prepare one and share with you shortly.

@charpeni you can find a repro at https://github.com/ipfs-shipyard/react-native-ipfs-demo. Check out branch repro/react-native-url-polyfill-#223.
Once the app starts up, press on the "ipfs.add()" button and then on the "add string" button. The error will be thrown at that point. You can trace the root cause to node_modules/react-native/Libraries/Network/FormData.js, line 109.

Ping @charpeni. Did you have a look at this in the meantime?

[charpeni]

@acostalima Sorry for the delay here! I'm struggling to find the time to work on this, but I'm definitely planning on looking at this as well as updating the whole package. To be honest, I think your patch seems like a good candidate, I just need to find the time to work on this.

[acostalima]

@charpeni no worries! Please take your time.

I can reproduce this exact same issue on RN 0.63.3.

@charpeni I've submitted a possible fix
