Hi Nicole,
When we upgrade the SAML module while doing so it will download the new jars as per the latest version but old version jars stays in the repo because of that this issue occurs .
Goto userlib folder in your app( Mendix\{Project}\userlib ) . Check the duplicate version of the jars like httpclient jars
Delete the older version and make sure you have single version of most of the jars related to SAML.
Clean your project from Studio Pro and Re Run .
I hope this will work for you .
After upgrading to Mendix 9.12.2 and SAML 3.6.1 (as well as all the dependent modules) I got the same error. Since my app is in production I didn’t want to delete everything. I went through deleting JAR files that had a newer version. The file that finally fixed it for me was jsoup-1.12.1, SAML 3.6.1 uses jsoup-1.15.3.
Hi Nicole,
I am also facing same issue.
could u please share the jar filename which u are deleted?
Thanks in advance
