## errors.SnapProcessingError


Processing a single burst or burst pair with SNAP failed.


Usage

``` python
errors.SnapProcessingError(
    *args,
    returncode=None,
    output_tail=None,
)
```


Raised when the GPT graph fails, and for an error staging the input SLCs or writing the product, which is kept as the cause.


## Parameters


`*args: object`  
The message, as for any exception.

`returncode: int | None = None`  
Exit code of `gpt`, negative for the signal that ended it.

`output_tail: str | None = None`  
The last lines `gpt` printed.


## Attributes


`returncode`  
Exit code of `gpt`, negative for the signal that ended it, such as `-9` for `SIGKILL`. `None` if `gpt` timed out or did not run, or the failure came from staging or writing.

`output_tail`  
The last lines `gpt` printed to stdout and stderr, or `None` if it printed nothing or did not run.
