Dheeraj Sudan & Meenu Hinduja - Chained App Fails After Server Upgrade Due to Incorrect..

Question

Hi everyone,

I’m Dheeraj Sudan from the UK. I’m a software developer and also run a business with my wife Meenu Hinduja. And I currently have a chained app published to the gallery. After a recent server upgrade, the app fails during execution.

App 1 generates two outputs using a relative path that should dynamically resolve to a temporary path on the user’s C:\ drive. However, when the workflow is run—either on the server or locally—App 2 attempts to retrieve files from **D:**, a path that does not exist anywhere in my workflow constants.

I have tried updating and replacing both the outputs in App 1 and the inputs in App 2, but the issue persists. App 2 continues to reference **D:**, and I’m unable to identify where this path is being pulled from.

Regards,
Dheeraj Sudan & Meenu Hinduja

Thank you so much for the detailed suggestions! I really appreciate the steps you've outlined. I will check the PHP version, update the dependencies, and review the error logs as you recommended. Hopefully, that will get the app working again. I will also make sure to look at the configuration files. Thanks again for your time and help—I will update you if I need any further assistance!

It seems like the chained app is failing due to incorrect configurations or compatibility issues following the server upgrade. A good first step would be to verify that the PHP version on the new server aligns with the version required by the app, as server upgrades can sometimes change PHP settings. Additionally, make sure all app dependencies are up to date and compatible with the new server environment. This could involve checking the version of libraries or frameworks that the app depends on. Reviewing server error logs might also give more insight into the issue—look for any specific error messages that point to missing files, incorrect configurations, or permission issues. Reinstalling the app’s dependencies, such as running a composer install, can also help resolve any issues caused by missing or outdated packages. Lastly, don’t forget to double-check configuration files, as server upgrades might alter critical settings like environment variables, database connections, or file paths. If you need more specific help, feel free to share any error logs or additional details, and I’d be happy to assist further.

Thanks for the tip! I will try hardcoding the C drive path in App 1 and then use a dynamic tool in App 2 to see if that resolves the issue.
