[warning] 145-145: MinVersionis missing from this TLS configuration. By default, TLS 1.2 is currently used as the minimum when acting as a client, and TLS 1.0 when acting as a server. General purpose web applications should default to TLS 1.3 with all other protocols disabled. Only where it is known that a web server must support legacy clients with unsupported an insecure browsers (such as Internet Explorer 10), it may be necessary to enable TLS 1.0 to provide support. AddMinVersion: tls.VersionTLS13' to the TLS configuration to bump the minimum version to TLS 1.3.

In `@main.go`:
- Around line 146-148: The tls.Config created as tls_config currently lacks an
explicit MinVersion, which can allow TLS 1.0/1.1; update the tls_config
initialization in the main's setup (where tls_config, http_transpot and client
are created) to set MinVersion to tls.VersionTLS13 (or at minimum
tls.VersionTLS12) so the HTTP client enforces a modern TLS minimum and prevents
downgrade to legacy protocols.
- Line 140: The header parsing at the req.Header.Add call uses strings.Split and
calls it twice, which truncates values containing colons; change this to use
strings.SplitN(element, ":", 2), store the split result in a local variable
(e.g., parts := strings.SplitN(element, ":", 2)), and then call
req.Header.Add(parts[0], parts[1]) to match the behavior of Validate() and avoid
duplicate splits.
- Around line 142-144: The else branch unconditionally calls
strings.Split(conf.Headers, ":")[1] which panics when conf.Headers is empty;
remove the entire else block so headers are only applied when conf.Headers is
non-empty, and update the header handling around req.Header.Add to first check
conf.Headers != "" (or use strings.SplitN(conf.Headers, ":", 2) and validate
length) before accessing the second element; target the conf.Headers usage and
the req.Header.Add call in main.go when making this change.

Let’s split first, check if there are two elements and then add the header.
This could cause an out of bounds error and kill the the minions

In `@main.go`:
- Around line 138-146: Collapse the two-branch header parsing into a single loop
over strings.Split(conf.Headers, ";") inside Run(), avoid calling strings.Split
twice, and use strings.SplitN(element, ":", 2) with a length check to prevent
panics for elements missing ":" (skip or return an error as per Validate()
behavior); also TrimSpace both header name and value before req.Header.Add so
values containing ":" are preserved and empty/trailing segments don't cause
index-out-of-range errors.
- Line 148: The tls_config currently created as tls_config :=
&tls.Config{InsecureSkipVerify: conf.Insecure} lacks an explicit MinVersion,
allowing TLS 1.0/1.1; update the tls.Config initialization (tls_config) to set
MinVersion to a safe minimum (e.g., tls.VersionTLS12) alongside
InsecureSkipVerify (e.g., include MinVersion: tls.VersionTLS12), so the
connection will reject older TLS versions; ensure the tls package symbol
(tls.VersionTLS12) is used and imports remain correct.

In `@main.go`:
- Around line 138-155: The runtime header-parsing in Run currently diverges from
Validate: it uses strings.Split and a conditional branch on
strings.Contains(conf.Headers, ";"), causing values with colons to be rejected
and duplicating logic; change the block that reads conf.Headers to mirror
Validate by removing the semicolon bifurcation, iterating over
strings.Split(conf.Headers, ";") and for each element using
strings.SplitN(element, ":", 2), validating len(parts) == 2, and then calling
req.Header.Add(parts[0], parts[1]) so inputs accepted by Validate() will be
accepted at runtime.
- Line 157: The tls.Config initialization for tls_config misses a MinVersion,
allowing TLS 1.0/1.1; update the tls.Config literal used where tls_config is
defined to include MinVersion: set MinVersion to tls.VersionTLS12 (or
tls.VersionTLS13 if you want to require TLS1.3) alongside the existing
InsecureSkipVerify: conf.Insecure so the config becomes a tls.Config with both
InsecureSkipVerify and MinVersion set (ensure you reference the crypto/tls
constants tls.VersionTLS12/tls.VersionTLS13).

Originally the headers would not execute unless the ContentType field was set to empty and the Headers string contained a semi-colon. Moved the logic and made it so the Headers executes if not empty now.
