Curl Works in Command Line, but Not Shell Script - bash

Question

I'm trying to automate a post-build process to get closer to a one-click release. However, I'm having problems with a script that.
Expected: The script to work exactly like the command line.
Results: Everything works, including grabbing the versionCodes except I am getting a curl: (26) Failed to open/read local data from file/application
The script I wanted to imitate with a more automated approach.
react-native bundle \
--platform android \
--dev false \
--entry-file index.js \
--bundle-output android-release.bundle \
--sourcemap-output android-release.bundle.map &&
curl https://upload.bugsnag.com/react-native-source-map \
-F apiKey=API-KEY \
-F appVersion=10.6.7 \
-F appVersionCode=4515 \
-F dev=false \
-F platform=android \
-F sourceMap=#android-release.bundle.map \
-F bundle=#android-release.bundle
react-native bundle \
--platform ios \
--dev false \
--entry-file index.js \
--bundle-output ios-release.bundle \
--sourcemap-output ios-release.bundle.map &&
curl https://upload.bugsnag.com/react-native-source-map \
-F apiKey=API-KEY \
-F appVersion=10.6.7 \
-F appBundleVersion=4515 \
-F dev=false \
-F platform=ios \
-F sourceMap=#ios-release.bundle.map \
-F bundle=#ios-release.bundle
So I wrote a script to fix this, which is
#!/bin/sh
# Ensure this is run on the commit used to generate the published app!
# Comment this line out to enable bundling and publishing
# debug=echo
bundle () {
platform=$1
$debug yarn react-native bundle \
--platform "$platform" \
--dev false \
--entry-file index.js \
--bundle-output "$platform-release.bundle" \
--sourcemap-output "$platform-release.bundle.map"
}
upload () {
platform=$1
version=$2
version_code=$3
# See https://docs.bugsnag.com/api/rn-source-map-upload/#uploading-source-maps
curl --http1.1 https://upload.bugsnag.com/react-native-source-map \
-F apiKey="$BUGSNAG_API_KEY" \
-F appVersion="$version" \
-F appVersionCode="$version_code" \
-F dev=false \
-F platform="$platform" \
-F sourceMap=#"$platform-release-bundle.map" \
-F bundle=#"$platform-release.bundle" \
}
read_version () {
local tag=$1
local file=$2
echo "$(grep -m 1 $tag $file | grep -o '[0-9]\+\(\.[0-9]\+\)*')"
}
BUGSNAG_API_KEY=$(plutil -p ios/RVLife/Info.plist | grep BugsnagAPIKey | awk '{ print $3 }' | sed 's/"//g')
if [[ -z $BUGSNAG_API_KEY ]]; then
echo "Couldn't find bugsnag API key"
exit 1
fi
IOS_VERSION=$(read_version MARKETING_VERSION ios/RVLife.xcodeproj/project.pbxproj)
echo "iOS app version: $IOS_VERSION"
IOS_VERSION_CODE=$(read_version CURRENT_PROJECT_VERSION ios/RVLife.xcodeproj/project.pbxproj)
echo "iOS version code: $IOS_VERSION_CODE"
if [[ -z $IOS_VERSION || -z $IOS_VERSION_CODE ]]; then
echo "Couldn't get iOS app versions"
exit 1
fi
bundle ios
upload ios "$IOS_VERSION" "$IOS_VERSION_CODE"
echo ""
ANDROID_VERSION=$(read_version versionName android/app/build.gradle)
echo "Android app version: $ANDROID_VERSION"
ANDROID_VERSION_CODE=$(read_version versionCode android/app/build.gradle)
echo "Android version code: $ANDROID_VERSION_CODE"
if [[ -z $ANDROID_VERSION || -z $ANDROID_VERSION_CODE ]]; then
echo "Couldn't get Android app versions"
exit 1
fi
bundle android
upload android "$ANDROID_VERSION" "$ANDROID_VERSION_CODE"
I'm assuming I messed up some syntax or permissions or something somewhere, but can't seem to find the area I did. Any help is appreciated.
Difference between bash -x myScript and set -x on command line
