I see the “Service Invocation” exercise twice. Is there an issue with the config or UUID? the config.json only has one entry for that exercise.
That’s due to the restoring of the exercise changing its UUID.
Old UUID: ballerina/config.json at 7db15a6338c1fe7dc38470586d8cbe936c562aed · exercism/ballerina · GitHub
Current UUID: ballerina/config.json at main · exercism/ballerina · GitHub
I’d suggest to use those commits to cross-reference the changed UUIDs and restoring them back to their original values.
