Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to version

Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to version 4.10.3, Parse Server crashes when if a query request contains an invalid value for the explain option. This is due to a bug in the MongoDB Node.js driver which throws an exception that Parse Server cannot catch.

There is a patch for this issue in version 4.10.3. No workarounds aside from upgrading are known to exist.
