I am trying to run _Cluster the intervals of a dataset_. The dataset was uploaded as a tab-delimited txt file with intervals (chr, start, end), with format set to interval. However, I keep getting an error, for instance.
_Uncaught exception in exposed API method:_
_The server could not complete this request. Please verify your parameter settings, retry submission and contact the Galaxy Team if this error persists. A transcript of the submitted data is shown below._

},

}_
I wonder what is wrong with the coordinates files, or there is a problem with the _Cluster_ tool? Though I keep getting a similar error message for tool _Complement intervals of a dataset_, thus the problem may rather be related to the intervals dataset.
Thanks in advance

Hi @jmuser
Thanks for sharing the tool errors. This might be due to a change on the server. I’ll try to test independently to replicate.
Are you working at [UseGalaxy.eu](http://UseGalaxy.eu) or at a different public server? Would you like to share your history?
- [FAQ: Sharing your History](https://training.galaxyproject.org/training-material/faqs/galaxy/histories_sharing.html)
Let’s start there! 🙂

Hi @jennaj,
Yes, I am encountering this problem at [UseGalaxy.eu](http://UseGalaxy.eu).
Here is the link to the history. **(Please keep private.)**
There are currently only two datasets with coordinates. Files/datasets without “#CHROM START END” produced the same error.
I just tested the Cluster tool with basically the same files/datasets at [UseGalaxy.org](http://UseGalaxy.org) — it works fine there.
Thanks a lot,
Jens

This is very likely a remaining issue from our recent configuration changes on Galaxy Europe.
We’ll look into it.

Turns out it was an older issue, but it’s now fixed for both Cluster and Complement.
Thanks for letting us know!
