# 3.23.0 Issues

### December 03, 2015 - 3.23.0 - Issues

As part of the latest release of BaseSpace, we have identified a few bugs as follows:

1. Projects with any character other than alphanumeric, underscore (`_`), or dash (`-`), will cause BCL2FASTQ 2.17 to fail. Since the latest BaseSpace release is using the same core algorithms, FASTQ Generation will fail if invalid characters are used. Users will see an error notification, and the log file will have details on the error.
   * As a temporary workaround: Users can remove the invalid characters OR make sure the column header in the SampleSheet Data section is called `SampleProject` NOT `Sample_Project` OR `SAMPLE_PROJECT`. PrepTab users with NextSeq will need to rename their Projects for the time being. Users will need to manually move Samples to existing Projects from newly created Projects.
2. For samples that have an underscore (`_`) in the name, the automatic conversion to a dash (`-`) in the file name, as occurred previously, is not occurring. As a result, a some apps may fail to launch.
   * A workaround for the time being is to rename the sample without the underscore, and requeue the FASTQ generation.
3. IGV is not opening projects and samples, because a BaseSpace API is failing.

We are working towards providing a fix for all of these as soon as possible.

## 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, and the optional `goal` query parameter:

```
GET https://help.connected.illumina.com/basespace/releases/previous-releases/2015/3.23.0.issues.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
