在AWS Systems Manager自动化文档中运行Bash脚本遇类型错误求助

我尝试使用AWS Systems Manager的自动化文档执行一段Bash脚本，但持续收到错误提示：is of type String, but expected type is StringMap，并附上了错误截图。我的自动化文档设置截图显示无法定义字符串类型，以下是按AWS要求在首尾添加单引号的脚本代码：

'#### errocodes'
'#### 0 hanadb state = OK'
'#### 10    hanadb state = STOPPED'
'#### 20    hanadb state = WARNING'
'#### 30    hanadb state = ERROR'
''
'# stop hana db'
'echo "Stopping Hana DB"'
'sudo /usr/sap/hostctrl/exe/sapcontrol -nr 00 -function Stop'
''
'# check hana db state'
'echo "Checking if Hana DB is running."'
'HANADBSTATUS=`sudo /usr/sap/hostctrl/exe/sapcontrol -nr 00 -function GetProcessList`'
'sleep 20'
'if [[ "$HANADBSTATUS" =~ "GRAY" ]]'
'then'
'    echo "Hana DB is stopped."'
'    exit 10'
'else'
'i=1'
'while [[ ! "$HANADBSTATUS" =~ "GRAY" ]] && [[ "$i" -lt 11 ]]'
'   do'
'       echo "Warning: HANA DB is running. Checking 10 times with 20 second intervalls until script aborts. This is check $i." '
'       sudo /usr/sap/hostctrl/exe/sapcontrol -nr 00 -function Stop'
'       sleep 20'
'       # check db state again'
'       HANADBSTATUS=`sudo /usr/sap/hostctrl/exe/sapcontrol -nr 00 -function GetProcessList`'
'       ((i++))'
'       if [ "$i" = 10 ]'
'           then'
'               echo "Error: retried $i-Times. Couldnt stop DB. Exiting Script."'
'               echo "Script aborts with Error 0"'
'               exit 0'
'       fi'
'   done'
'   if [[ "$HANADBSTATUS" =~ "GRAY" ]]'
'    then'
'        echo "Hana DB is stopped."'
'        exit 10'
'   fi'
'fi'

问题原因与解决方法 #

核心原因 #

这个错误是由于SSM自动化文档中参数类型不匹配导致的：某个被定义为StringMap类型的参数，你传入了普通的String值；或者你需要用String类型的参数，却被强制设置成了StringMap。

解决步骤 #

1. 检查参数类型配置
   找到报错对应的参数，确认其类型是否为StringMap。如果是，你需要传入键值对格式的内容（例如{"key": "value"}），而非纯字符串。

2. 调整脚本传入方式
   如果无法修改参数类型（如你所说无法定义字符串类型），可以将脚本内容包装成StringMap格式，比如用固定键存储脚本：

   {"script_content": "你的完整脚本内容"}
   

   然后在自动化文档的执行步骤中引用该键对应的值（例如{{ script_content }}）。

3. 修正脚本格式
   你当前的脚本每行都被单引号包裹，这会导致Bash执行失败。正确做法是去掉所有行的单引号，同时把转义的"替换为普通双引号，修正后的脚本如下：

   #### errocodes
   #### 0 hanadb state = OK
   #### 10    hanadb state = STOPPED
   #### 20    hanadb state = WARNING
   #### 30    hanadb state = ERROR
   
   # stop hana db
   echo "Stopping Hana DB"
   sudo /usr/sap/hostctrl/exe/sapcontrol -nr 00 -function Stop
   
   # check hana db state
   echo "Checking if Hana DB is running."
   HANADBSTATUS=`sudo /usr/sap/hostctrl/exe/sapcontrol -nr 00 -function GetProcessList`
   sleep 20
   if [[ "$HANADBSTATUS" =~ "GRAY" ]]
   then
       echo "Hana DB is stopped."
       exit 10
   else
   i=1
   while [[ ! "$HANADBSTATUS" =~ "GRAY" ]] && [[ "$i" -lt 11 ]]
      do
          echo "Warning: HANA DB is running. Checking 10 times with 20 second intervals until script aborts. This is check $i." 
          sudo /usr/sap/hostctrl/exe/sapcontrol -nr 00 -function Stop
          sleep 20
          # check db state again
          HANADBSTATUS=`sudo /usr/sap/hostctrl/exe/sapcontrol -nr 00 -function GetProcessList`
          ((i++))
          if [ "$i" = 10 ]
              then
                  echo "Error: retried $i-Times. Couldnt stop DB. Exiting Script."
                  echo "Script aborts with Error 0"
                  exit 0
          fi
      done
      if [[ "$HANADBSTATUS" =~ "GRAY" ]]
       then
           echo "Hana DB is stopped."
           exit 10
      fi
   fi
