Have you ever encountered “An internal server error has occurred” in Salesforce . You’re in the middle of a critical task in Salesforce updating a record, running a report, or deploying a change set and suddenly, your screen goes white and internal server error message appears: “An internal server error has occurred” accompanied by a long, seemingly random string of numbers and letters called an Error ID.
It’s frustrating and can stop you in your tracks. So, what does an internal error has occurred mean? And more importantly, what should you do when an internal server error occurred? Lets dive in our Salesforce Hours .
What is an “Internal Server Error”?
Let’s get one thing straight, this error is almost never your fault . When an internal server error has occurred, it indicates that something unexpected went wrong on Salesforce’s own servers. It’s an unhandled exception an error that the Salesforce platform itself didn’t anticipate and couldn’t gracefully recover from.
Think of it like a car’s engine suddenly seizing up for a reason the driver can’t see. The car stops, and a warning light comes on, but the dashboard doesn’t tell you why it seized.
Meet the GACK Error : Your Golden Ticket for the Error ID
That long Error ID you see with the internal server error message is your most valuable piece of information. Salesforce refer to this as a GACK error.
A GACK error is not just a random code, it’s a unique fingerprint of the exact error that occurred. It contains encrypted information about:
- The specific server (pod) where the error happened.
- The exact time of the error.
- The stack trace, which points to the precise line of code in the Salesforce core application that failed.
You can’t decode this information yourself, but Salesforce Support can. The GACK is the key that allows their engineers to instantly look up the failure in their logs and diagnose the root cause of the an internal server error.
What Causes a Salesforce GACK?
While you can’t see the direct cause, these errors are typically triggered by:
- A bug in a new Salesforce release: Sometimes, new updates can introduce unforeseen issues.
- Complex operations: A very complex SOQL query, a convoluted Apex transaction, or a Flow hitting an obscure limit might cause a part of the platform to fail.
- Interacting with specific data: In rare cases, a specific data pattern in a record could trigger a bug in Salesforce’s code when it tries to process it.
- Pilot or Beta feature issues: Using new features can sometimes uncover bugs that haven’t been ironed out yet.
The key takeaway is that a GACK is different from a standard error you might see from a validation rule, a Flow error email, or a handled Apex exception. Those are errors within your configuration. A GACK is an error within Salesforce’s platform.
Your Step-by-Step Action Plan
When you encounter an internal server error, don’t just refresh the page and hope for the best. Follow these steps to ensure a swift resolution.
Step 1: Document Everything Immediately
Before you do anything else, capture the evidence.
- Take a Screenshot: A picture is worth a thousand words.

- Copy the Full Error ID (GACK): This is critical. Select the entire string of numbers and letters and copy it to a notepad.
Example : “An internal server error has occurred Error ID: 1288274194-119575 (-1785955966)”

- Note the Exact Time: Record the date and time the error occurred.
- Record the Steps to Reproduce: Write down exactly what you were doing.
- What button did you click?
- What record were you on?
- What were the values you entered?
- Were you running a specific report or a piece of Apex code?
Step 2: Try to Reliably Reproduce It
Can you make the error happen again by following the same steps?
- Is it consistent? If it happens every single time, it’s a high-priority bug.
- Does it affect other users? Ask a colleague to try the same steps.
- Does it happen in a Sandbox? Try to reproduce the error in a sandbox environment. This can help isolate the cause.
If you can’t reproduce it, it may have been a transient, one-time hiccup on the server. If it’s reproducible, proceed to the next steps.
Step 3: Check Salesforce Trust
Before you assume the problem is unique to your org, check the official Salesforce status page.
- Go to Salesforce Trust.
- Find your instance (pod) and see if there are any known performance degradations or incidents. The error you’re seeing might be part of a wider issue Salesforce is already working on.
Step 4: Log a Case with Salesforce Support
This is the most important step. The GACK is designed to be given to Salesforce Support.
- Go to the Salesforce Help portal and create a new case.
- Provide all the information you collected in Step 1:
- The Subject Line: Make it clear, e.g., “Internal Server Error – GACK – When Saving an Opportunity.”
- The Error ID: Paste the full GACK into the case description.
- Steps to Reproduce: Provide your detailed, step-by-step instructions.
- User Impact: Explain who is affected and what business process is blocked.
- Grant Login Access: Grant Salesforce Support login access to your org so they can investigate.
With the GACK, the engineer can bypass many of the initial troubleshooting questions and get straight to the root cause, leading to a much faster resolution.

Conclusion
While seeing an “Internal Server Error” is alarming, it’s also one of the most straightforward errors to deal with if you know what to do. Remember: the Error ID (GACK) isn’t for you to solve it’s your direct line to a solution from Salesforce.
By staying calm, documenting the details, and logging a comprehensive support case, you turn a frustrating dead end into a clear path toward resolution.
