You are using a shell syntax feature not supported by the script's shell. Either rewrite the construct, or switch to a different shell interpreter.

ShellCheck 0.10.0 and below warns about ${ ..; } command expansions when using Bash. However, Bash 5.3 added support for this construct. If you are using this construct in Bash 5.3, either ignore the warning or upgrade ShellCheck.
