# What can I do when I got rendering error message? (List below)

When rendering reports through Carbone Cloud API & Studio, it is possible to receive error messages and it is due to design issue inside the template.

**If one of the following error occurs, read [the Style Guide checklist](https://help.carbone.io/en-us/article/style-guide-to-design-a-report-z8lv57/).**

List of common errors:
* `Error: could not open document` : The generated document is corrupted due to a design issue, it can come from tags, loops, formatters, conditional blocks, dynamic colors, or dynamic pictures.
* `Error: Cannot read property 'position' of undefined` :  It is most of the time a loop issue, probably a missing `[i]` or `[i+1]`. To learn more about loops: https://carbone.io/documentation.html#repetitions
* `Error: 'part2start' of null`: Loop issue or conditional block issue when using "showBegin/showEnd" or "hideBegin/hideEnd"
* `Error: Formatter "imageFit" does not exist. Do you mean "int"?`: This error occurs when a formatter is either misspell or the formatter is not available on the Carbone version you are trying to use. In this case, imageFit is only available on the version 3 of Carbone.
