Help with JSON regex replace

Command:

rex mode=sed "s/\"name":\s\"[^\"]+\"/"name":"###############"/g"

Regex seems to work fine in Regex101 

However, I seem to continue to get this error:

Error in 'SearchParser': Missing a search command before '^'. Error at position '69' of search query rex mode=sed "s/\"c...{snipped} {errorcontext = n_id"\s\"[^\"]+\"/"co}'.

I'm trying to mask a json key:value pair.  See below:

"name": "john doe" ----> "name": "######"

Hello,

It is missing a after the name and before the ".

The correct one is:

| rex mode=sed "s/\"name\":\s\"[^\"]+\"/"name":"###############"/g"

Thank you for this.  For some reason I had to add a few more \ to make this work.  See below:

“s/\”name\”\:\”[^\”]+\”/\”name\":\"###############\"/g"

Hello,

Thank you for the reply.  That removed that error.  However, it still doesn't mask the "name" field in the search.

"name" still shows as:  

"name": "john doe"

ah.  I figured it out.  I had to modify it like the following for it to replace properly:

“s/\”name\”\:\”[^\”]+\”/\”name\":\"###############\"/g"

This is using splunk cloud btw.
