That's kind of like the life story of user manuals and users

The relay is an SRD-05VDC-SL-C.
The datasheet says the nominal coil current is 71.4 but even if connect directly to 5V 62 mA flows, i hope that is not an issue.
Measure the coil resistance if possible. If something is well out of spec..... then see what happens if you use another module of identical variety .... to make sure everything at least conforms with specs.
Also..... use a multimeter to measure the input voltage across the coil .... to see if it is 5V DC.
