### Search before asking - [x] I had searched in the [issues](https://github.com/apache/seatunnel/issues?q=is%3Aissue+label%3A%22bug%22) and found no similar issues. ### What happened # Description: ## Bug Description When parsing CSV data that contains escape characters (e.g., \"), the CSV parser fails to correctly parse the line and returns all fields as null instead of the actual values. ## Affected Component Module: seatunnel-format-text Class: CsvLineSplitor Steps to Reproduce Read a CSV file containing fields with escaped quotes, for example: ``` String line = "1, name: \\\"tyrantlucifer\\\"" ``` Parse the CSV line using the CsvLineSplitor Observe that all fields are returned as null Expected Behavior The parser should correctly handle escape characters and return: Field 1: 1 Field 2: name: "tyrantlucifer" Actual Behavior All fields are returned as null. ## Root Cause The CSVFormat configuration in CsvLineSplitor.java does not specify an escape character. When the Apache Commons CSV parser encounters a backslash (\) without a configured escape character, it fails to parse the line correctly. ## Solution Configure the CSVFormat to explicitly set the escape character to backslash: ```java CSVFormat.DEFAULT.builder().setDelimiter(splitChar).setEscape('\\').build() ``` ### SeaTunnel Version 2.3.9 ### SeaTunnel Config ```conf env { parallelism = 1 job.mode = "BATCH" } source { FtpFile { host = "127.0.0.1" port = 21 user = "user" password = "123" path = "/path/to/csv/file" file_format_type = "text" delimiter = "," schema = { fields { index_field = int desc_field = string } } } } sink { Console { } } ``` ### Running Command ```shell seatunnel.sh -c run.conf -m local ``` ### Error Exception ```log print all column is null ``` ### Zeta or Flink or Spark Version _No response_ ### Java or Scala Version _No response_ ### Screenshots _No response_ ### Are you willing to submit PR? - [x] Yes I am willing to submit a PR! ### Code of Conduct - [x] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
