How to Handle Errors and Warnings in Make.com

When you build automations in make.com, understanding how errors and warnings work is essential for keeping your scenarios reliable and easy to maintain. This guide explains what errors and warnings are, how they appear, and how to respond to them step by step.

What Are Errors and Warnings in Make.com?

During execution, a make.com scenario can run into problems or potential problems. These are shown as errors or warnings in your run history and logs.

Errors in make.com scenarios

Errors represent issues that prevent a module or scenario from completing a task successfully. When an error occurs, the affected operation fails and is logged with detailed information.

Common characteristics of errors include:

• The operation does not finish as expected.
• You see an error icon in the scenario run.
• Execution details show the error message and type.
• They may stop the scenario run, depending on configuration.

Warnings in make.com executions

Warnings indicate that something unexpected or suboptimal happened, but the module or scenario could still continue. They are less severe than errors, but still important to investigate.

Typical characteristics of warnings:

• The module runs, but with a potential issue.
• You see a warning icon in the run log.
• Execution details provide more information about the warning.

Where to Find Errors and Warnings in Make.com

To handle issues effectively, you must know where to look inside the make.com interface.

Scenario run history in make.com

Each time your scenario runs, make.com creates an entry in the run history. Use this to track when errors and warnings occur.

1. Open your scenario.
2. Click the History or Runs section.
3. Select a specific run to view its timeline.

In the timeline, modules with problems are highlighted with special icons for easier identification.

Module-level execution details

From the run history timeline, you can click individual modules to see what happened.

1. Click the module with an error or warning icon.
2. Open the Details or Inspector pane.
3. Review input bundles, output bundles, and error or warning messages.

This helps you pinpoint whether the problem came from input data, connection settings, or external services.

Common Types of Errors in Make.com

Although the interface may show many messages, errors in make.com usually fall into a few broad categories.

Connection and authentication errors

These errors occur when a module cannot connect to an external service.

• Expired tokens or revoked access.
• Incorrect API keys or credentials.
• Missing permissions for a requested action.

To fix them, reauthorize the connection, update API credentials, or adjust permissions in the connected app.

Configuration errors in modules

These errors typically result from incorrect settings or missing fields in your module configuration.

• Required fields left empty.
• Invalid field formats (for example, wrong date formats).
• Referencing fields that do not exist in the incoming data.

Review the module setup, compare it with the incoming data structure, and adjust the configuration accordingly.

Data and validation errors

Data errors happen when the data passed between modules does not match what the target module expects.

• Wrong data type (text where a number is required).
• Values outside allowed ranges.
• Invalid or malformed values, such as email or URL formats.

Address these issues by adding tools modules (such as formatters or transformers) to clean and validate data before passing it to the next module.

How to Diagnose Errors in Make.com Step by Step

Use a structured approach to find the root cause of an error in a make.com scenario.

1. Identify the failing module

In the run history:

• Look for red error icons in the execution map.
• Note which module first shows an error; this is usually where to start.

2. Read the error message carefully

Open the module details and focus on:

• The error text and code (if available).
• Hints about the external service response.
• Which field or operation triggered the failure.

3. Check input and output data

In the same detail view, inspect:

• Incoming bundles going into the module.
• Any partial outputs generated before the error.

Confirm that the data structure and values are what you expect at this point in the scenario.

4. Reproduce and retest in make.com

After you adjust configuration or data mapping:

1. Run the scenario again, ideally with the same test data.
2. Monitor the run history to see if the error reappears.
3. If needed, add more logging or temporary modules to output intermediate data.

How to Respond to Warnings in Make.com

Warnings do not usually stop execution, but they can highlight areas where your make.com automations may become unstable in the future.

Evaluate the impact of a warning

When you see a warning icon:

• Open the run details and read the warning message.
• Check if any data was skipped, truncated, or adjusted.
• Determine whether the warning affects business logic or outputs.

Decide whether to adjust the scenario

Some warnings are acceptable; others require changes. You might:

• Add validation steps before critical modules.
• Improve error checking on external data.
• Change configuration to avoid ambiguous behavior.

Best Practices for Stable Make.com Scenarios

You can reduce errors and warnings in make.com by designing scenarios with stability in mind.

Plan data flow and structure

• Define expected data formats early.
• Add transformation modules to standardize values.
• Use consistent naming and mapping for fields.

Use logging and inspection tools

• Insert helper modules to log key values.
• Regularly review run histories, even for successful runs.
• Document complex branches and decision points.

Monitor external dependencies

• Track rate limits and quotas on linked services.
• Set up alerts for frequent or repeating errors.
• Reauthorize connections before tokens expire.
