I've got Uchiwa on-screen but it is flashing the error I mentioned.
Tailing the sensu-api log doesn't reveal much:

at least, not to me.
The api config is:
[root@ws00 sensu]# cat conf.d/api.json
{
"api": {
"host": "localhost",
"port": 4567,
"user": "sensu",
"password": "REDACTED"
}
}
Next, there's the output of the health checks they talked about on their github (https://github.com/sensu/uchiwa/blob/master/README.md):
/health
{"uchiwa":"ok","sensu":{"Sensu":{}}}
/health/sensu
{"sensu":{"Sensu":{}}}
/health/uchiwa
{"uchiwa":"ok"}
The clincher?
service sensu-api status
reports it is running happily along, no worries.
At any rate, Google doesn't return anything for "Error with Sensu API Sensu" so I hope you folks can help!
If a look at other configs would be handy, let me know.
Another possibility is the location of your uchiwa.json file.
I had a similar issue and didn't know what was going on but it seemed to have issues when I had the uchiwa.json file created in /etc/sensu/conf.d but at the same time the default configuration created an uchiwa.json file in /etc/sensu. For some reason uchiwa wants the file to be in /etc/sensu and for now I am happy with that configuration as it finally has the api working correctly. Good luck to you.
