# Troubleshooting

Midio is still in early development, and there will inevitably be bugs. Here is a list of known bugs, and some workarounds.

## Execution error: Failed to consume context

This error can occur if you’ve put nodes that either consume or borrow from their execution context inside your own functions. Examples of functions like this include [`Response`](/midio-docs/built-in-nodes/http.md#response) and `Testing.Assert`. You can see what contexts a node requires by hovering its input trigger. See [Contexts](/midio-docs/reference/the-midio-language/contexts.md) for more information, and [Contexts](/midio-docs/reference/the-midio-language/contexts.md#how-it-works) for how you can make your own function use them. The quick fix is to add the EndpointContext to your functions input trigger consumes section.

## Error notifications when trying to perform edits

This might mean that the editor server or engine has crashed. Try refreshing the browser.

## 502 when sending HTTP request to the editor

This can happen if the URL is malformed, like for example of the port number is not in the right location. Make sure to put the port before the resource part of the url, for example: **https\://\<my-project>.midio.dev:\<port-number>/some/resource**

## Internal error when trying to delete module with types that are referenced from other modules

The compiler will fail if it is not able to resolve all types, and the editor won’t save changes that cause the compiler to fail. That is why this notification will appear if you try to delete a module with a type that is in use by functions in another module. A workaround until we streamline this case is to first change all uses of that type to another type first, and then try again.

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://docs.midio.com/midio-docs/troubleshooting.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
