Instabug source map upload returns 500 Internal Server Error

[naveen-pf]

Hi Instabug team,

I'm trying to upload source maps for React Native using your https://api.instabug.com/api/sdk/v3/symbols_files endpoint.

Here’s the relevant part of my code that generates the sourcemap and uploads it via curl:

`const {execSync} = require('child_process');
const {getConfig} = require('@expo/config');
const path = require('path');

const {exp} = getConfig(process.cwd());
const args = process.argv.slice(2);

const channel = args.includes('--channel')
? args[args.indexOf('--channel') + 1]
: 'staging';

const platformList = ['ios', 'android'];

const appVersion = process.env.APP_VERSION || '1.0.0';
const buildNumber = process.env.BUILD_NUMBER || '10001';
const environment = channel === 'production' ? 'production' : 'staging';
const instabugToken =
channel === 'production'
? exp.extra.instabugKeys.Production
: exp.extra.instabugKeys.Staging;

const codePushVersion = execSync('git rev-parse --short HEAD')
.toString()
.trim();

console.log(📦 App Version: ${appVersion});
console.log(📦 Build Number: ${buildNumber});
console.log(📦 Environment: ${environment});
console.log(📦 CodePush Version: ${codePushVersion});
console.log(📦 Instabug Token: ${instabugToken});
console.log(📦 Channel: ${channel});

console.log(🔁 Running EAS Update for channel: ${channel}...);
// execSync(npx eas update --channel ${channel} --non-interactive --message "OTA Update for ${channel}", {
// stdio: 'inherit',
// });

console.log('📦 Bundling and uploading source maps for Instabug...');

platformList.forEach((platform) => {
const bundleDir = ./dist/bundles/${platform};
const entryFile = 'index.js';
const sourcemapPath = path.resolve(${bundleDir}/${platform}-sourcemap.json);
const bundlePath = path.resolve(${bundleDir}/index.${platform}.bundle);

// Step 1: Bundle the app
execSync(
npx react-native bundle \ --entry-file ${entryFile} \ --platform ${platform} \ --dev false \ --bundle-output ${bundlePath} \ --sourcemap-output ${sourcemapPath} \ --assets-dest ${bundleDir},
{stdio: 'inherit'},
);

// Step 2: Upload using curl
const versionJson = JSON.stringify({
name: appVersion,
code: buildNumber,
codepush: codePushVersion,
});

const curlCommand = curl --trace-ascii ./instabug-curl.log --fail-with-body -X POST https://api.instabug.com/api/sdk/v3/symbols_files \ -F "symbols_file=@${sourcemapPath}" \ -F "application_token=${instabugToken}" \ -F "platform=react_native" \ -F "os=${platform}" \ -F "app_version=${versionJson}";

console.log(📤 Uploading source map for ${platform}...);
execSync(curlCommand, {stdio: 'inherit'});

console.log(✅ Source map uploaded for ${platform} platform.);
});
`

❌ Problem
The API returns:

{"status":500,"error":"Internal Server Error"}

Even though the sourcemap and bundle are valid files, and the upload appears to succeed (no curl error).

I’ve already added --trace-ascii to get internal curl logs, but the response body is not helpful beyond the 500.

Can you help identify what could be wrong or validate whether the app_version format or file MIME type could be causing the 500?

Thanks!
Naveen
