I don't have hardware to debug this , try building with appengine build tag and see if it fixes it

[Zariel]

also can you post your go env, does this replicate on go 1.13?

[eclipseo]

Yes this replicate in go 1.13: https://koji.fedoraproject.org/koji/taskinfo?taskID=41332999

try go build -tags appengine

[funny-falcon-at-joomcode]

Sure it cause of endianess , and appengine should be fine there. ... except it is broken: LittleEndian has no method Int64.
