Unable to perform actions with AWS Timestream (Endpoint Discovery failed)

Hi there,

Which boto3 and botocore are you using? Can you try to upgrade them to the latest version? Also Is it possible to post a code snapshot of your Python code and AWS CLI?

I am using v1.24.19 for boto3 and v1.27.19 botocore. I tried upgrading them to the latest version (v1.24.21 and v1.27.21) but I get the same error.

Below is my client creation code. I have used the same code to assume a different role with a different profile for S3 before and it worked fine. session = boto3.Session() roleClient = session.client('sts') assumedRole = roleClient.assume_role(RoleArn=roleARN, RoleSessionName='role') credentials = assumedRole['Credentials'] awsKey = credentials['AccessKeyId'] awsSecretKey = credentials['SecretAccessKey'] awsSessionToken = credentials['SessionToken'] client = boto3.client( 'timestream-write', aws_access_key_id=awsKey, aws_secret_access_key=awsSecretKey, aws_session_token=awsSessionToken, )

For writing it's just the one line of code for testing:

result = self.client.write_records(DatabaseName=self.database, TableName=self.table, Records=records, CommonAttributes={})

I tried setting the database and table names to empty strings and it gives the same error so it's failing before it gets to check those variables. For the AWS CLI, I used the example from the docs:

aws timestream-write create-database --database-name myFirstDatabase
