Index already exists error when recreating a bucket

I am seeing this error after updating to couchbase (2.2.4) pip package

Server version (5.0.0-2873, 3 nodes)

Steps to repro

• Delete bucket with Primary Index defined
• Recreate the bucket
• Create an index using the code below

 
b = Bucket("couchbase://{}/{}".format(self.host, bucket), password='password')
found_ids = []
b.n1ql_query("CREATE PRIMARY INDEX ON `{}`".format(bucket)).execute()
for row in b.n1ql_query("SELECT meta(`{}`) FROM `{}`".format(bucket, bucket)):
    log_info(row)
    if row["$1"]["id"].startswith(prefix):
    found_ids.append(row["$1"]["id"])
 
Sometimes (more often than not), the N1QL index creation fails with the following error.
E HTTPError: <RC=0x3B[HTTP Operation failed. Inspect status code for details], HTTP Request failed. Examine 'objextra' for full result, Results=1, C Source=(src/http.c,140), OBJ=ViewResult<rc=0x3B[HTTP Operation failed.
