Snapshot does not open with IO exception

[mdskk14]

I am trying to collect a CPU Sampling snapshot on YourKit-JavaProfiler-2025.3-b135-x64 with my apps running on JDK 17 and JDK 21

I am using below commands to generate the snapshot

curl -k -X POST https://localhost:10001/yjp/api/v2/startSampling

curl -k -X POST https://localhost:10001/yjp/api/v2/capt ... ceSnapshot

When i try to open the snapshot i run into below error,


perf-yk.snapshot is not a valid snapshot file
"I/O exception: Protocol message had invalid UTF-8"


I validated the chksum and size of the snapshot post copying and they are the same
