Remove or trim FileSource from json
we have a Fluid-Condition which does not match on empty FAL "source" field, although source is empty in DB. Debugging in Fluid told me: String "" (CHAR: 1). Yeah...funny. I have tryed it a second time on DB with: SELECT uid, HEX FROM sys_file_metadata WHERE uid=345 which now returns 03.
Hmmm. 03 is CTRL+C, but it also can be an indicator for a starting UTF-8 letter.
I have found following document: http://exif.org/Exif2-2.PDF It's a meta description of Ex-If.
FileSource Indicates the image source. If a DSC recorded the image, this tag value of this tag always be set to 3, indicating that the image was recorded on a DSC. Tag = 41728 (A300.H) Type = UNDEFINED Count = 1 Default = 3 3 = DSC Other = reserved
As you can see 3 is default and it does not make sense to extract this HEX-Code 1 to 1 into DB. Right?
