Flutter run --profile crash on open Chrome's Flutter devtools

When I run app in --profile mode and open flutter devtool app crash with Exception right after Chrome load the screen. Debug mode works without issues. Reproduces on Flutter 2.0.3 and 2.0.5 same.

Fyi @bkonyi. Another vm service crash in profile mode.

[bkonyi]

We're seeing this with such frequency that I think we're going to have to hack around this in DevTools. We'll need to guard calls to getSourceReport behind a profile/release mode check somehow.

[bkonyi]

Workaround up for review in #2986.

I just ran into this with Flutter 2.0.6

What is the most recently Flutter version that wasn't affected by this bug? If it's not too old, maybe downgrading Flutter can be a workaround.

Downgrading Flutter won't help unless you go back > 2 years. We need to publish a hotfix with #2986 included to work around this in DevTools.

I will do this now.

2.2.2 is released, so this issue should be fixed with that version of DevTools.

[InMatrix]

How do I use the 2.2.2 version of DevTools? Is it sufficient to upgrade to the latest Flutter version on the master channel?

[RogyBear]

I have the same question as InMatrix. When I tried to run the 2.2.2 version of DevTools with Flutter version 2.0.6 in profile mode, I ran into the same error that @InMatrix provided above.

[ObranS]

Issue reproduces with version 2.2.2

$> pub global activate devtools

will upgrade devtools version

[InMatrix]

@isemic Thanks!

I no longer experience this problem when using v. 2.2.2 of DevTools.
