Extract a substring - powershell

Question

I am trying to get proper error message which is there in description. But when my debugger enters into substring line its getting exited with no reason.
$job= submitting the job 2fdab2d5-f09c-4392-953e-8b85f90d76eb ...
client version: 10.2.2.0
target: cluster
stat: simulatelarge
skippath: true error submitting job.
vcclientexceptions.vcclientexception: [httpstatuscode = 0; description = e_csc_user_syntaxerror: syntax error. expected one of:_all _and ';' ')' ','
description: invalid syntax found in the script.
resolution: correct the script syntax, using expected token(s) as a guide.... at token [output], line 13 near the ###:
$descpos = $job.IndexOf("description:")
$resopos = $job.IndexOf("resolution:")
$descmsg = $descmsg.Substring($descpos)
Write-Host $descmsg
$ferrormsg = $job.Substring($msgpos,$respos+1)
Write-Host $ferrormsg
WORKING - CODE:
[string]$Result=$job
$Result= $Result -Replace "[\{]|(\{)|[\}]|(\})|[\""]|(\"")",''
$msgpos = $Result.IndexOf(("message:") )
$resopos = $Result.IndexOf(("resolution:") )
$descpos = $Result.IndexOf(("description:") )
$ferrormsg = $Result.Substring($msgpos,($descpos-$msgpos) )
$ferrormsg = $ferrormsg -Replace "(\,)|(\')|(\-)|(\=)",''
Write-Host $ferrormsg
THANKS ALL ,
Replaceing my string is working fine.

Try this
$job= "submitting the job 2fdab2d5-f09c-4392-953e-8b85f90d76eb ...
client version: 10.2.2.0
target: cluster

skippath: true error submitting job.
vcclientexceptions.vcclientexception: [httpstatuscode = 0; description = e_csc_user_syntaxerror: syntax error. expected one of:_all _and ';' ')' ','
description: invalid syntax found in the script.

$descpos = $job.IndexOf("description:")
$resopos = $job.IndexOf("resolution:")
$ferrormsg = $job.Substring($descpos,$resopos-$descpos)
Write-Host $ferrormsg
