I got this error in nDPI (https://oss-fuzz-build-logs.storage.googleapis.com/log-cc7ee201-ad7d-4fb5-bbf8-969abbc8bab1.txt).

I have been seeing these error for a few days, but until recently the build stopped before that point for another issue (now fixed). Bottom line: I don't know if this issue is new or not...

Anything I can do from my side?

It seems the same error already reported #13473
