`source` is undefined when SvgXml calls the parse function within xml.tsx

source is undefined when SvgXml calls the parse function within xml.tsx

Bug

ERROR [TypeError: Cannot read property 'length' of undefined]

Unexpected behavior

source shouldn't be undefined or parse function should handle source optionally

Steps To Reproduce

This is the code I'm using to load an Svg

                    <SvgUri uri={uri}
                        width={size}
                        height={size}
                        preserveAspectRatio="xMidYMid meet"
                        style={[styles.avatarImage, sizeStyle]}
                    />

This is the URI I'm trying to load https://res.cloudinary.com/merkle-manufactory/image/fetch/c_fill,f_png,w_256/https://openseauserdata.com/files/d5d652ed260e8c7891f731cad05805d4.svg

I am experiencing the same issue.

I'm having the same issue with a URI as well. The problem is that both the OP's URI and mine end with .svg but actually return .pngs when requested. When fetchText() tries to load that URI's SVG XML and instead receives a binary blob, it just returns undefined for the text (something that shouldn't technically be possible according to the types).

Facing same issue with url and it is breaking with error Cannot read property "length" of undefined

Hello @decpk @mitchelljustin @abraham-serafino @manan19,

I have reviewed your issue and I believe it has been resolved.

Here is a branch with a test case.

Perhaps I overlooked something. Please feel free to check and let me know if everything is working as expected.

Thank you!
