T.data is not iterable error when integration grafana with cloudwatch

I am new to grafana but I will try summarize what I wish to achieve.

I need to setup a grafana dashboard which queries information from Cloudwatch regarding 32 different product versions. (I cannot query the DB directly and I can only rely on the cloudwatch logs)

I am currently running 32 different queries with each query having the Product name as a filter value.

Sometimes, the panel fails with “t.data is not iterable”.

Reading a few other threads, I understood that this is a problem caused by the concurrency limits from cloudwtatch side.

What I would want to know is if there is better way to resolve this?

→ I can create multiple panels but how do I make sure that they get loaded sequentially only?
