Hey… I know I’m not the first (or fiftieth) person to ask about this, but I did something maybe uniquely dumb, which was to use a firebase backend for Expo, so that now I really can’t upload any images. I’ve been trying work arounds all day (on hr 11 right now) to no luck. Things I’ve attempted:
-
using XHR to convert the local file into a blob or an Int8Array and then posting that to firebase.storage().ref(). This returns the error: ‘TypeError: One of the sources for assign has an enumerable key on the prototype chain. Are you trying to assign a prototype property? We don’t allow it [etc]’.
→ I’ve discovered that this seems to be an error with Object.assign() and react-native, which I am not calling anywhere, but which is perhaps being called under the hood by firebase. So there goes that approach. -
using a separate backend for images, such as a rails server. The problem here is that, when sending a local file to a local server running even on the same computer, the local server can’t find the file. (‘No such file or directory @ rb_sysopen file:///Users/Ian/Library/Developer/CoreSimulator/Devices/’).
→ This is perhaps something to keep looking into… I thought about posting a blob or byte array to rails, using the XHR trick, but it doesn’t work either, given that I get the same TypeError when using fetch with blobs. Is this an error with all blobs? I don’t think so, so maybe I’m missing something–perhaps the blob returned by the XHR trick (It’s xhr.responseType = ‘blob’, and you send the xhr to grab your local file), isn’t the same as an actual blob?. -
using cloudinary for direct image hosting. You can post fetch requests to cloudinary, and I even got this working briefly, but the issue was that I couldn’t do it with my signed account, just my unsigned one. And if you post with an unsigned key, cloudinary doesn’t return the URL, so that ended up being fairly useless.

this fix with scaphold.io (https://gist.github.com/allpwrfulroot/7539e58ad6a8258d78e8f4808f513cad). Now, granted, I’m brand new to scaphold.io (and to mobile dev, which may be one reason I’m having all these problems), but I couldn’t seem to post anything to scaphold successfully… I kept getting my requests denied without quite figuring out why. Maybe that’s one I should watch the tutorial on.
Any advice except to kind of keep trucking through this? Check out Scaphold more, maybe I’ll find a solution there?
Thanks!
