Workdocs does not recognize the Excel files as the files are pushed from S3 bucket and using S3 to Workdocs architecture

I have enabled microsoft enabled in workdocs but still I see strange behaviour with Amazon workdocs were it is not reading the file and cant edit it on Workdocs.

The file is pushed from S3 bucket which gets the file from another lambda function which creates and pushes the file to S3 bucket which is linked with workdocs.

When I upload the same file in the S3 bucket directly it goes to Workdocs and works fine only when the preprocessed file comes from lambda than only it doesn't work. I feel most possible the issue with how I push file to s3 bucket thecode must be something different or I dont know hat is the big problem. Please let me know

S3 to Workdocs article: https://aws.amazon.com/blogs/storage/auto-sync-files-from-amazon-s3-to-amazon-workdocs/

Lambda code to create and push the excel file to s3 bucket:

    bucket_name_output = 'sf-data'  -- sample name
    file_key_output = 'sf_check_daily_upload/ssot_dev.csv000'


    ########### SF check data read ############# 
    
    response_sf = s3.get_object(Bucket=bucket_name_output, Key=file_key_output)
    csv_content_sf = response_sf['Body'].read().decode('utf-8')
    df_sf = pd.read_csv(io.StringIO(csv_content_sf))
    
    df_sf.to_excel('/tmp/sf_check_data.xlsx', sheet_name='SF_check', index=False)
    
    s3 = boto3.client("s3")
    s3_resource = boto3.resource("s3")
    s3_resource.Bucket("carts-sf-s3toworkdocs-data-source").upload_file('/tmp/sf_check_data.xlsx', 'carts_sf_ssot_data/sf_check_data.xlsx')
