InvalidArgumentException: URI must be a string or UriInterface

[Saša Stamenković]

After pushing GuzzleRetryMiddleware with max_retry_attempts: 3, retry_on_timeout: true, I get:

InvalidArgumentException:
URI must be a string or UriInterface

It works without GuzzleRetryMiddleware.

It was the issue in my code, sorry for the noise.

@umpirsky glad to hear you got it worked out!

[Soheb Somani]

Hey @umpirsky I'm facing the same issue in one of my unit tests.. Could you tell me how you figured this out?

[Saša Stamenković]

Sorry, can't remember, it was more then a year ago.

[Casey McLaughlin]

Hey @soheb-somani... author here! If you'll provide more details on the context, I'll try to help out.

When encountering this issue, try double-checking what are you passing in as variable. When I encountered this, the configuration in the environment that was failing passed null instead of a URL.
