I also tried to download a checkpoint file from the storage bucket manually, and then tried to import the stack from this file, but this command also fails:

pulumi stack import --file ~/Downloads/pulumi_history_experiments_experiments-1574820036002431000.checkpoint.json

error: could not deserialize deployment: unexpected end of JSON input

What are the contents of that file? Is it legal JSON? How did you get that file?

Yes, it was generated by pulumi before. I've just been able to import the stack successfully with the

--force

flag:

pulumi stack import --disable-integrity-checking --file ~/Downloads/pulumi_history_experiments_experiments-1574820036002431000.checkpoint.json --force

Huh - that is very unexpected. Yes - an issue would be great - especially if it’s something you can reproduce.

Tried a

pulumi up --refresh

afterwards, and hit an exception actually. I'll add details in a github issue.
