Input file has “LF” character. I am getting error message while reading the file.
Please help me to handle "LF"character if there is any way.
Hi,
This is configurable on you metadata. You just need to open up the metadata editor (double click on the metadata name in the Outline window) and select
\n
as the record delimiter - this is the escape sequence for line feed (LF). You can do this either one by one for each field separately or you can change it for all the fields at once by setting it on the Record line (the first line in the table) → Record delimiter.
\r\n
is the default one - matching CR/LF (carriage return and line feed). You can also choose any character sequence as your delimiter if need be.
If changing the delimiter doesn’t help, please attach the whole run log.
Best regards.
I have done the same thing as you mentioned but still I am getting error message.
I am using charset “ISO-8859-1” for data reader.

Okay, this is a different error and is not related to the record delimiter (\r\n vs. \n) but the field delimiter. It appears the fields in the file are delimited by comma, whereas the default field delimiter is pipe |. I just realized I made a mistake in my previous explanation. The record delimiter can be changed via editing the “Record delimiter” property of the Record line in the metadata editor or by editing the “Delimiter” column of the last field. On the contrary, the field delimiter can be changed via “Default delimiter” property of the Record line or by the “Delimiter” column of the Record line (both are applied to all fields without specific settings) or by changing the “Delimiter” column for each field separately except the last field. I hope it makes sense.
So if the fields in the input file are really delimited by comma, you need to change the field delimiter (Default delimiter) to comma as well.
Hope this helps.
I have same metadata setting as mentioned. But Still I am getting error while reading the file.
Please refer attached screenshot of Metadata.
Okay, basically, if it’s still the same error: “Unexpected record delimiter, probably record has too few fields.”, it means there’s a mismatch in the expected number of fields and the actual number of fields coming from the input file. Can you please attach an example input file that causes this issue. I would like to see if there’s anything wrong with the file and hopefully create an example graph that would be able to read it.
Thank you in advance.
I have attached input .csv file. File has “LF” character as end of line.
Hi,
I’m not sure if you’re aware of that functionality but you can actually extract metadata from the input file. I did exactly that on your input file and it works flawlessly. Attached is an example graph that works with your file. You can test it in your environment and compare it to your graph.
Let me know if the graph works for you as well, please.
Best regards.
I don’t know what was the issue, I just removed “\n” from Delimiter column of last line of metadata and graph is working fine.
Initially I had manually entered “\n” in the Delimiter column of last line of metadata and it was showing in highlighted mode. And graph was not working. After removing “\n” from last line, “\n” is still showing there but in shadow form (not highlighted), and graph started working.
I have done this after viewing your graph. In your graph “\n” was in shadow form in the Delimiter column of last line of metadata.
I hope I am making sense what I am trying to say. Any idea why Clover behaves this way?
Thank You for help and input.
Hi,
I just found out this is a feature of the metadata configuration as per the documentation. I must admit it’s confusing and I didn’t know about this feature either. On the other hand, it might be useful for certain corner cases.
Best regards.
Thank You. Seems configuration rule.
