You appear to be initializing or appending an array element to an associative array without giving it an index. In an indexed array, elements will be auto-indexed by incremented characters. In associative arrays, the index must be given explicitly.
This could happen because of invalid spaces or otherwise malformed
index assignment, such as array=( [key] = value )
. This
should instead be array=( [key]=value )
.
ShellCheck may be confused when a variable name is reused in different contexts. If shellcheck mistakenly believes the array is associated, please ignore this error.
