Can't start washer - "expecting property name enclosed in double quotes"

[Particpant]

Describe the bug
When trying to start my washer, which has previously worked, I'm getting an error: "Failed to call service button/press. Expecting property name enclosed in double quotes: line 1 column 27 (char 26).
My dryer continues to allow for remote starts.

Expected behavior
Remote start button on washer device in home assistant triggers a remote start.

Additional context
I see that a new version has released today, I'll be trying that and updating the bug shortly.

Here's a log (I get the same error) on v0.38.4.
Dryer remote start still works, the washer's pause and power off commands also work, and all the sensors seem to work as well.

Here's the diagnostic.
The logs above were all debug enabled. There's an attached file in the initial post. Let me know if you need me to try any specific steps while debug logging is enabled. Here it is again https://github.com/ollo69/ha-smartthinq-sensors/files/14395492/smarthinq.log.txt

Thanks for building out the integration, btw!

[ollo69]

No, thanks, this should be enough, I already see the issue in the log.
I'll work on this...

[ollo69]

Please try new release, it should fix the issue.

[Particpant]

Confirmed fixed in v0.38.5
