trustAnchors parameter must be non-empty

[Kris Miller]

Hi-

This is my first post. I am fetching a url - census data - and in my newly created column I get this error "java.lang.RuntimeException: Unexpected error: java.security.InvalidAlgorithmParameterException: the trustAnchors parameter must be non-empty". I'm using Ubuntu 18.04. How do I fix the error?

Hi Kris,

What version of OpenRefine did you download and use ?

Can you give us the url that you are fetching with, if you don't mind ?  It will help us troubleshoot.

Hi Chris,

That's an SSL error that is probably due to the fact that your Java
installation is too old. You should be able to fix the issue by
upgrading your Java JRE.

Hi-

I tried the same fetch on version 2.8 and 3.0. 

I also purged java and the certificates and reinstalled them. I'm using the default java for Ubuntu

java --version yields:

openjdk 10.0.1 2018-04-17

OpenJDK Runtime Environment (build 10.0.1+10-Ubuntu-3ubuntu1)

OpenJDK 64-Bit Server VM (build 10.0.1+10-Ubuntu-3ubuntu1, mixed mode)

 

A sample of the url I tried fetching is: https://api.census.gov/data/2016/acs/acs5?get=B25063_003E&for=block+group:1&in=state:26+county:077+tract:006702&key=c4c2a4ceccbe416e7c495b01fac47e8f9889f315

This is a request to the Census API for 2016 ACS data. The request returns a JSON object when the url is put in Chrome. 

Hope this gives everyone more insight. Thanks

Kris

Hi,

Have you tried copying the cacerts file from the Oracle distribution?

I found a fix. I removed default jre and jdk and the openjdk-11 and only installed openjdk 8.

Thank Kris 

Updating java solved our problem too.
