Incoming webhook payload is empty due to script compilation failure

[mkd2380]

When storing JavaScript scripts for the bot in the Rocket.Chat, the bot was sending empty payloads.
Upon inspection, the database-stored script had a syntax error and the compiled field was empty.
Manually compiling the script in the database resolved the issue, and the bot started processing webhooks correctly

Description:

Steps to reproduce:

1. Go to 'Integrations'
2. Click on 'New for creating Incoming WebHook Integration'
3. write your scripts and save

Expected behavior:

Scripts stored in the database should compile automatically and execute correctly, so that webhook payloads are processed as expected.

Actual behavior:

The bot fails to process webhooks because the stored script does not compile. The compiled field in the database is empty until manually compiled

Server Setup Information:

• Version of Rocket.Chat Server: 7.13.1
• Number of Users: 20
• Operating System:
• Deployment Method:
• Number of Running Instances: 1
• NodeJS Version: v22.16.0
• MongoDB Version: 7.0.15 / wiredTiger (oplog Enabled)

Additional context

This issue highlights that database-stored scripts may fail to compile automatically if there is a syntax error or missing Babel plugin. Manually compiling the script in the database resolves the issue.

Error [BABEL] unknown file: Cannot find module '@babel/plugin-syntax-nullish-coalescing-operator'
While processing: "base$0$0"

can you assign me?

Hi there !
I noticed this is caused by a missing Babel plugin in the build environment.

Since Node v22 supports nullish coalescing natively, we can likely remove the plugin requirement from the Babel config, or simply add @babel/plugin-syntax-nullish-coalescing-operator to the dev dependencies to resolve the module not found error.

I can open a PR to add the dependency if this issue is still open for contribution.

Hi there ,
We are facing a similar issue. New webhooks are not working, and there is no error visible in the Rocket.Chat logs. The incoming webhook message appears empty. However, we found a script processing error in the database.

I tested this issue and was unable to reproduce the bug.

Environment:

• Rocket.Chat Version: 7.14.0-develop
• Node.js: v22.16.0
• OS: Fedora
• Browser: Microsoft Edge

Test Results:

Tested both the Prometheus script from the comments above and modern JavaScript syntax (nullish coalescing ?? and optional chaining ?.). Both legacy and modern scripts compiled and executed successfully.

It appears this may have been fixed in recent commits.

[kevin-aidevlabs]

I can confirm this is happening in 7.13.2. I didn't dare to touch the database, downgrading to 7.12.2 and saving the scripts in it worked.

[shiavm006]

Hi! I'd like to work on this issue
As @KrishCodesw mentioned, since Node v22 supports nullish coalescing natively, we should configure Babel to target the Node version being used. This way Babel won't try to transpile features that are already native.
