# unsupported_file

The file is not a kind that can be converted.

## What happened

Conversion accepts MQL5 source files, with the extensions `.mq5` and `.mqh`, sent as the raw body of the request. Anything else, or a request with no file body, is refused with 400. The reply can carry a `reason`.

## What to do

Send the indicator's own `.mq5` source file, or an `.mqh` file it includes.

## Example

```json
{
  "error": "A raw file body is required.",
  "code": "unsupported_file"
}
```
