composer error trying to get the correct compatable versions

[inpresif]

I'm getting this error after fixing the guzzle6-adapter issue earlier. Not getting this to work.

Problem 1
- php-http/guzzle6-adapter is locked to version v2.0.1 and an update of this package was not requested.
- xsolve-pl/salesforce-client[1.0.0, ..., v1.0.3] require php-http/httplug ^1.1 -> satisfiable by php-http/httplug[v1.1.0].
- Conclusion: don't install php-http/httplug v1.1.0 (conflict analysis result)
- Root composer.json requires xsolve-pl/salesforce-client ^1.0 -> satisfiable by xsolve-pl/salesforce-client[1.0.0, v1.0.1, v1.0.2, v1.0.3].

Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.

No luck with composer require xsolve-pl/salesforce-client -W either
