Unable to create integrations with Fuse Online Operator 7.6 / Fuse Online (1.9.0.fuse-760020-redhat-00001)

I successfully installed Fuse Online 1.9.0.fuse-760020-redhat-00001 on Openshift 4.3.5 using the Fuse Online Operator v7.6 via the OperatorHub page. The application deploys successfully. Unfortunately, when you deploy any simple integration, the s2i build fails with the following error message:

[ERROR] Failed to execute goal on project project: Could not resolve dependencies for project io.syndesis.integrations:project:jar:0.1-SNAPSHOT: The following artifacts could not be resolved: com.squareup.okhttp3:okhttp:jar:3.14.4.redhat-00001, com.squareup.okio:okio:jar:1.17.2.redhat-00002: Could not find artifact com.squareup.okhttp3:okhttp:jar:3.14.4.redhat-00001 in central (https://repo.maven.apache.org/maven2/) -> [Help 1]
