You need to return a dictionary with one of the specific values the webdev module understands - you don't directly return text from your webdev function: > **[Web Dev | Ignition User Manual](https://docs.inductiveautomation.com/docs/8.1/ignition-modules/web-dev#return-value)** > > The Web Dev module enables you to directly program against the web server inside the Ignition Gateway. Webpages can be built by hand using a combination of Python programming and static web resources such as images, CSS files, JavaScript files, and... As in: `return {'response': u"Año: 25 | Mes: 2"}` ---

This code is not executing in your browser, it is executing on your gateway. `console.log` is not a valid function. Use a logger from `system.util.logger` to log the values to your gateway log file for inspection. > **[system.util.getLogger | Ignition User Manual](https://www.docs.inductiveautomation.com/docs/8.1/appendix/scripting-functions/system-util/system-util-getLogger)** > > Returns a Logger object that can be used to log messages to the console. You are receiving the 500 error due to the invalid function you are attempting to call. Your gateway logs should also show a warning or error stating such. ---

> [@kennethandrad](#): > > javascript (SERVER) This seems to indicate a fundamental misunderstanding of _something_ on your part. Can you take a step back and describe the _general_ problem you are trying to solve via the Webdev module? ---

The problem I had was that I couldn't get any return data, but I solved it with the JSON format. When I called, I forgot to include the .py file in the web address, otherwise I would keep getting an error. Thanks to everyone.
