OEM 13.4 AgentPull.sh failed with '0403-011 The specified substitution is not valid for this command'

When using Oracle Enterprise Manager 13.4 AgentPull.sh to deploy Agent 13.4 on AIX server, got following error,
./AgentPull.sh[270]: platform=${platform/\)/%29}: 0403-011 The specified substitution is not valid for this command.

Line 270 in AgentPull.sh is
platform=${platform/\)/%29}

It is a bash statement which tries to replace right parenthesis with code '%29', it works for bash but not Bourne shell (sh). The problem is that the script has directive to have Unix/Linux to run the script under bourne shell
$ head AgentPull.sh
#!/bin/sh

The script works on most Linux servers because the /bin/sh is a symbolic link file linked to /bin/bash on these servers. Unfortunately, AIX is honest :), sh is sh and bash is bash, they are different.

As workaround, replace first line of AgentPull.sh '#!/bin/sh' with '#!/bin/bash'.
