Hello Muthusamy, Reegan,

Thank you for reaching out.

To help investigate the issue, could you please provide a few more details?

Which keys are not being populated (for example, host keys, function keys, or system keys)?

Does this occur for all deployment slots or only specific ones?

Which hosting plan is the Function App using (Consumption, Premium, or App Service Plan)?

Has this behavior always occurred, or did it start recently?

Are there any errors or warnings in Log stream, Diagnose and solve problems, or Application Insights (if enabled)?

Could you also confirm that the AzureWebJobsStorage application setting is configured correctly for the affected slot?

This information will help us better understand the issue and assist you further.

Thank you!

I have had this issues before. Depending on the version of Functions you are using and what keys are not showing up. My case was the app keys showing greyed out. What helped me and my team is to check verify if the settings for the Azure Storage for functions are correct (any typo, etc. seems to make a difference) and the run-time version of functions on the configuration
