why does the ld.get_data() not return anything for commodity options

tim_hannon

for example, ld.get_data('C430X25', fields=['EXPIR_DATE'])

I used item code from data item browser.

Many thanks

Thank you for reaching out to us.

For me, it returns data properly.

You may need to enable the debug log by running the following code before opening a session.

config = ld.get_config()

config.set_param("logs.transports.file.enabled", True)

config.set_param("logs.transports.file.name", "lseg-data-lib.log")

config.set_param("logs.level", "debug")


ld.open_session()

With this code, the lseg-data-lib.log file will be created.

Please remove any private information or credentials from the log file before sharing it. Once we have the log, we’ll be able to investigate the issue further.

Hi, i believe session is definitely established as I can use other lseg.data.content functions well and ld.get_date() works well as the example shown in the github. See attached screenshot.

It is a permission issue.

You can try this delayed RIC (/C430X25) instead.

 ld.get_data('/C430X25', fields=['EXPIR_DATE'])
