TypeError: coercing to Unicode: need string or buffer, Key found. I get this error when I try to run the following line in python
bucket = conn.get_bucket("bucket_name")
for key in bucket.list("field_test_27_06_20/cameras/", "/"): # print "{name}\t{size}\t{modified}".format( # name = key.name, # size = key.size, # modified = key.last_modified, # ) if str(key.name).endswith(bag_to_be_searched): print(str(key)) bag = rosbag.Bag("bucket_name/key")
It would be grateful If you can help me in this
