That's an odd error message - but it does suggest your stack file got corrupted somehow.  You will likely need to find a copy of the state file from before this one that is still "correct" and then run `pulumi refresh` to catch it up with what's in your cloud and then `pulumi update` to update again.

The issues with the state file getting corrupted are likely specific to the filestate backend (S3/GCS) - as noted also in the answer to <https://pulumi-community.slack.com/archives/C84L4E3N1/p1596488417410900?thread_ts=1596230652.357900&amp;cid=C84L4E3N1>.
