Serialized closure is not signed on Production Server

[jayakusumah]

[QUESTION].

Versions

• PHP version: PHP 7.2.19-0ubuntu0.18.10.1
• Laravel version: 5.7
• Package version: 3.1

Description

I get this error when the queue export

local.ERROR: The serialized closure is not signed. Make sure you use a security provider for both serialization and unserialization
my code
(new MemberExport)->queue($fileName);

Work on local but error on server.

Additional Information

Just follow official documentation (queued export)

The fact that it works local, but not on production might be due to APP_DEBUG set to true.
See this comment on another package about a similar issue.

Hey @jayakusumah I can't really reproduce the issue, but reading different issues about the same error message I came to the following fix: #2257
Can you test if this fix works for your situation?
