MongoDB migration does not work.

[surister]

Running a migr8 command with a simple document {"text": "hola"}
migr8 export --url "mongodb://root:[email protected]:27017" --database test_db --collection test_col

Gives:

(.venv) ~/PycharmProjects/crate/cratedb-toolkit git:[main]
migr8 export --url "mongodb://root:[email protected]:27017" --database test_db --collection test_col
Traceback (most recent call last):

Thank you so much! If you are at it, can you also have a look at that other error report?

• MongoDB: Error while using translate ValueError: max() iterable argument is empty #134

This no longer happens in master, when I came across this;

cratedb-toolkit/cratedb_toolkit/io/mongodb/export.py

Line 106 in b7b8010

for document in collection.find():

document was a dict, now it's correctly a bson document and doesn't fail.

Excellent, thank you! So, the package needs a release to make it work? I can't remember anything has been changed in mongodb/export recently, but if you are effectively saying that the most recent release package does not work, a new release would be needed indeed.
