mongorestore to documentdb error

Question

I am testing offline migration from MongoDB to DocumentDB using mongodump/mongorestore and got the following error:

`mongorestore --username  --password  \
 --uri="mongodb://my-documentdb-cluster.cluster-abcd1234.us-east-2.docdb.amazonaws.com:27017" \
 –-sslCAFile rds-combined-ca-bundle.pem --db  /var/lib/mongodb/dumps/dump

2022-02-03T09:54:15.042-0500	error parsing command line options: error parsing positional arguments: provide only one polling interval in seconds and only one MongoDB connection string. Connection strings must begin with mongodb:// or mongodb+srv:// schemes
2022-02-03T09:54:15.042-0500	try 'mongorestore --help' for more information`

Where did I do wrong?

Thanks in advance!

Answer

The main reason you are seeing "error parsing positional arguments" is the first '-' in '–-sslCAFile' is actually a [Unicode EN DASH](https://www.fileformat.info/info/unicode/char/2013/index.htm).

Also, it's not clear in the original post if this is a multi-line or single line command. Use the `\` character only for multi-line input.

2 other changes to make are:

1. use `--host` option instead of `--uri`
 2. add `--ssl` option

The command should look like the following:

`mongorestore -ssl --username  --password  \`

`--host="mongodb://my-documentdb-cluster.cluster-abcd1234.us-east-2.docdb.amazonaws.com:27017" \`

`--sslCAFile rds-combined-ca-bundle.pem --db  /var/lib/mongodb/dumps/dump`
