Advanced Foundry: Create Deployment Script. Running this test testConvertSvgToUri() reverts

[kelechukwu1]

Hi,
I coded along as I watched Patrick, but in the end, my test fails with the message I attached at the end of this thread.
Hi, I am at this section of the course, I coded along but when testing for testConvertSvgToUri(), it reverts with an error, if anyone can help me look into my code, I'll be happy.
##Here are the codes below:

Thank you @EngrPips, the test passes now, I really do appreciate.

Meanwhile, I created this discussion earlier mistakenly when I signed in to github with my companies new github account, here is the discussion number #3515, please can you help me delete the discussion so it won't appear in my new companies github activity chart please?

I tried to delete it, but could not see any delete option, so I edited it to remove the question and closed it.

please help me delete it completely.

[EngrPips]

@Equious sir, can you help with this.

[kelechukwu1]

Sir @Equious please help me here

[Equious]

Should be deleted now.

[kelechukwu1]

Thank you so much my bosses @Equious & @EngrPips
