Issue with regex used to identify clickhouse error messages

[mike-luabase]

The regex used to catch error messages from the clickhouse server is missing error codes with 3 digits e.g. error code 215. The change below would fix it, but I don't know clickhouse well enough to determine if this will cause other issues.

const R_ERROR = new RegExp('(Code|Error): .*Exception: (.+?)$', 'm');

@TimonKK is there any reason we need to keep the ([0-9]{2})[,.] part of the regex?

I see you updated here in September, can we drop the # check?

What do you mean about "drop the # check"?

[mike-luabase]

@TimonKK the current regex is checking if there are numbers (([0-9]{2})[,.]) in the error code, is that necessary? If so, it'd need to check for at least three digits.

I know ClickHouse has two digital error codes, for example, ClickHouse/ClickHouse#33839. So I think to adjust regexp to '(Code|Error): ([0-9]{2,})[,.] .*Exception: (.+?)$'

@TimonKK The problem is there are now three digit error codes, e.g. I got 215

I understood about three-digit error codes. And I suggested new regexp /(Code|Error): ([0-9]{2,})[,.] .*Exception: (.+?)$/. You could test it on https://regexr.com/
