Is there a grep, sed or awk one liner that would remove lines from a regular expression to the next blank line?

Looking at a huge log file that list errors. The log file prints the type of error and then some details. The number of lines in the details can vary but there is always a blank line after.

Example:
Result after filter to remove type2 error and it's details:

Things get a bit more complicated with grep. There are lots of grep-like tools, some of them better suited to the task on hand than others. Broadly speaking, I'd divide tools I deem "well-suited" in this context into three categories. Sadly, GNU grep (or any traditional grep implementation) is in no one of these.

First, tools that can operate on paragraphs rather than on lines of text: greple (written in Perl) and paragrep (written in Python). Their only disadvantage is that they are lesser known and rarely provided by Linux distributions, so you may have to install them from CPAN and PyPI, respectively.
Then, there's sgrep which is a category in and by itself. It's an old tool, last updated in 2004, but still surprisingly useful at times. Beware though that despite its name, sgrep doesn't understand regular expressions. So, "type2" in the example below is a literal string.
Lastly, there are tools that 1) allow matching across the lines, AND 2) allow -v/--invert-match to be used while doing so. For example, pcregrep that comes with the PCRE library, or ripgrep:

Hi Shruggy,

Thanks for the quick reply. Unfortunately our systems do no have pcre2grep, rg, or sgrep installed and I'm not the sysadmin so I can't install them.

The sed and awk commands did not filter out anything. It's probably my fault. I implied that the RE would be at the beginning of the line and that is not necessarily the case.

So if you want a detailed answer you need to provide detailed info on what should be the target to be filtered. We can only work on the info you provide and our suggestions will only be as accurate as is the info we have to work with.

Please post an exact input line/ group of lines that the code should work on.

No probably about it.
shruggy went above and beyond IMHO - how about you make some effort yourself. This should be a good opportunity to learn. 99% of the answer has been given to you. I would suggest sed would be simplest, with least to have to learn along the way.

And you were given practically the same sed solution in one of your previous threads.

The following does not need a last end condition (empty line).
