I have multiple sub-charts under a single composite/umbrella chart. What could be the possible reasons for this error? Are there constraints with the sizes of a particular yaml? What should at most have 1048576 bytes? What can be the possible solutions so that more charts can be added to the composite/umbrella chart?
Secrets are limited to 1MiB in size as described here:

What are you trying to encode into a secret that makes it >1MiB?
