Invalid value ` ` for

Error message

Invalid value `{config_value}` for `{config_entry}`

What it means

FrontendError::InvalidConfigValue: a session/system config entry was set to a value that fails validation for that entry (e.g. non-numeric value for an integer setting). Fired by the config-setting path when the new value is rejected; the faulty input is the (config_entry, config_value) pair.

Solutions

1. Read config_entry and config_value in the message to find the offending session/system parameter.
2. Use SHOW PARAMETERS or the documentation to list valid values for that parameter.
3. Re-issue SET with a supported value.
