TypeError: m[0].map is not a function Error Message

[gcobb321]

I am trying to set up a simple list table that will take attributes within en entity and list them and am having a problem getting it working. Below is a sample of the attribute and how I have setup the card. I'm running HA 0.90.1. When the invalid function error is displayed, the card disappears from the lovelace screen.

Am I missing something?

I am the developer of the icloud3 device_tracker program (go here for information about it) so I can change the program if something related to how the attribute list & dictionary is set u is needed. My goal is to keep an event log of significant events while determining the location of an iphone and then display them. Since I'm keeping this log im memory, only the last 400 entries will be kept.

jinja query and result: {{ states.sensor.icloud3_event_log.attributes.eventlog }}

mmmh, there is no error check (yet) to verify that there is actually a list inside the attribute refered in attr_as_list, as this is actually how the error is looking like.

Did you try?

• just use attr_as_list without modify and only one column, what is shown?
• accessing the attribute without list interpretation (attr) and then use modify to select the first entry (and the desired member) within the list?

Thanks for the reply. I went in another direction.
